The log data indicates normal resident activity: waking up, checking the door, and routine evening routines, with no evidence of forced entry or unauthorized access.

Explanation: Occupancy sensors confirm the house was empty (0) from 00:00 to 05:38, ruling out early morning intrusion before the resident woke up at 05:38.

Explanation: The manual lock at 06:58 occurred exactly when bedroom occupancy turned '1', indicating the resident entered and secured the door themselves.

Explanation: The subsequent immediate auto-unlock at 06:58:08 confirms the system recognized the authorized user and corrected a transient state, consistent with normal operation rather than a breach.

Explanation: No motion sensors triggered in the entrance hall between the window closing (05:38) and the first lock event (06:58), eliminating the possibility of an intruder hiding inside.

Explanation: The second manual lock at 08:31 coincides with kitchen occupancy turning '1' (likely preparing breakfast/coffee), representing another routine check by the resident.

[2026-06-05T06:58:04] bedroom_occupancy | OccupancySensing.Occupancy = 1

No occupancy events in entrance_hall between 05:38 and 06:58

Continue monitoring standard daily patterns.

No immediate action required; the system is functioning as expected.

[2026-06-05T06:58:08] ... LockOperation(Auto): System automatically unlocked the door shortly after manual lock, suggesting resident presence or system glitch correction.

[2026-06-05T20:39:14] ... LockOperation(0, Auto): Normal evening auto-lock behavior.

Room activity counts are distributed across all rooms, consistent with a single occupant moving through the house.

Manual locking events occurring immediately after the window closes at 05:38 while the resident might still be settling in or if they were not present to trigger the 'Auto' unlock logic so quickly.

Window tampering or attempted access: The bedroom window position changed rapidly between 12:21 (fully open/closed cycle?) and 13:56 (closed). Specifically, the log shows `10000` (likely fully open or a specific state code) at 12:21 and 20:39, then `0` at 13:56. Rapid cycling of windows can indicate someone trying to gain leverage or checking visibility without entering.

No corresponding high room_activity count specifically for the bedroom during these times compared to other rooms; however, total activity is low overall.

Check raw motion sensor data (`occupancy_sensor`) for the entrance hall and bedroom between 05:30 and 08:30 to confirm if anyone entered the house manually.

Verify the timestamp accuracy and synchronization of the front door lock and bedroom window sensors to rule out clock skew causing false temporal correlation.

Inspect the `LockOperation` source details for the manual locks at 06:58 and 08:31 to see if they correspond to a key fob, physical key insertion, or app command from an unknown device ID.

Review video footage (if available) or check for sound/anomaly alerts triggered near the front door during the 06:58-08:31 window.

中等可信度警报，建议住户确认是否本人操作

No anomaly detected; the log shows a consistent daily pattern of household departure during the day and return in the evening with normal sensor behavior.

Explanation: Occupancy sensors correctly reported '0' from 12:00 to 16:05, confirming the house was empty during daytime hours.

Explanation: At 16:07, occupancy sensors registered presence (Bedroom=1, LivingRoom=1) immediately following a door lock event with UserIndex=1, resolving the previous paradox where a user action occurred without prior occupancy detection.

Explanation: The temperature spike at 18:10-18:40 corresponds to an HVAC activation upon resident return, which is a standard normal response and not indicative of fire or malfunction.

[2026-06-17T16:07:05] bedroom_occupancy | Occupancy = 1

[2026-06-17T18:10:45] kitchen_temp_sensor | TemperatureMeasurement.MeasuredValue = 2581

Continue standard monitoring; no intervention required.

Verify smart lock logs if specific user attribution (UserIndex) remains inconsistent in future reports.

Inconsistent user source attribution: The first door lock event at 16:07 lists 'UserIndex=1', implying a specific user action, whereas the subsequent events are 'Manual' and 'Auto'. If UserIndex=1 corresponds to a known resident, their presence should trigger occupancy sensors; however, the log shows continuous 'Occupancy=0' from 12:00 onwards, creating a paradox where a specific user interaction is logged but no physical presence is detected by motion sensors.

[2026-06-17T16:07:00] front_door_lock | Event: LockOperation(..., UserIndex=1)

Timestamp mismatch between Occupancy=0 (starting 12:00) and UserIndex=1 lock event (16:07): How did the user interact with the door if they weren't detected inside?

Sequence at 22:04: Bedroom curtains fully closed (privacy mode?) followed immediately by Auto-locking of the front door, potentially trapping occupants inside or indicating an unmonitored entry/exit cycle.

High concentration of lock operations (3 events in ~4 hours) compared to typical daily usage patterns for a single-family home.

Raw motion sensor data stream around 16:00-16:10 to confirm if UserIndex=1 physically triggered the sensor or if it was a phantom signal/false positive.

The exact definition of LockOperationType=0 vs Type=1 and whether Type=0 represents 'Unlock' or just 'Status Update'.

Whether the 'Auto' lock event at 22:04 was triggered by a magnetic contact closure (door physically shut) or a timer/security routine.

Temperature logs to see if there was any heating/cooling adjustment when the curtains were closed at 22:04, which might indicate human presence adjusting comfort settings.

The sustained occupancy signal is explained by normal human behavior (cooking and cleaning in the kitchen while sitting/resting in the living room), supported by corroborating appliance logs.

Explanation: The 'stuck' occupancy sensor hypothesis is refuted by strong evidence of human activity in other rooms: the kitchen cook surface was turned off at 19:43 and the dishwasher started at 19:56, indicating active cooking/cleaning duties.

Explanation: The temperature readings show a significant spike in the kitchen between 18:15 and 18:55 (reaching ~27°C/80°F+ relative to baseline), consistent with heat generation from appliances used during that window.

Explanation: The pattern of high frequency kitchen light on/off events and specific appliance operations confirms physical presence, validating that the resident remained in the home performing routine tasks rather than simulating presence.

中等可信度警报，建议住户确认是否本人操作

The automated security sequence (window closing followed by door locking) is a confirmed routine triggered by legitimate user presence in the bedroom at night, not an intrusion or unauthorized access.

Explanation: Evidence shows occupant presence (Occupancy=1) in the bedroom at 23:09:10, immediately preceding the window closure and subsequent door lock.

Explanation: The 'Auto' lock source is validated as a reaction to the detected occupancy change (user returning home), consistent with standard smart-home automation logic.

Explanation: No signs of forced entry, sensor malfunction, or contradictory motion data were found; the pattern aligns perfectly with H2 (standard nighttime routine).

Explanation: Contrast with the morning entry at 10:13:00 which used a specific UserIndex (8/1), confirming that manual vs. auto locks are both functioning correctly based on context.

[2026-06-27T23:09:10] bedroom_occupancy | OccupancySensing.Occupancy = 1

Verify the configuration history of the 'front_door_lock' to ensure 'Auto' locking is enabled and triggered by expected conditions (e.g., garage door close, specific timer, or app command).

Cross-reference with network logs to see if there was a remote API call to the home automation system around 23:09:14-17.

The sequence of events indicates a resident's normal evening routine: opening the bedroom window for ventilation followed by leaving the house and auto-locking the front door upon exit.

Explanation: Occupancy sensors show continuous presence in the bedroom until 23:11:05, immediately preceding the window opening.

Explanation: The front door contact sensor triggered (StateValue=True) at 23:11:25, just one second before the auto-lock command was issued at 23:11:26, confirming the lock was triggered by an authorized user exiting.

Explanation: The subsequent action of turning off the bedroom light at 23:11:30 is consistent with a resident leaving the premises after ventilating the room.

[2026-06-20T23:11:25] front_door_contact | BooleanState.StateValue = True

No immediate action required; log event as 'Normal Routine' in security audit.

Verify that the 'Auto' lock source configuration correctly maps to geofence exit or door-open triggers if not already documented.

## Focused Raw Log

凌晨2:30-2:40短时间内多房间连续活动 活动轨迹：客厅→厨房→玄关（像在搜索什么） 卧室全程无活动（住户在睡觉），这些活动不是住户产生的 注意区分：如果卧室先有活动再到其他房间，则可能是住户起夜

Evidence indicates a forced entry or tailgating attempt at the front door between 07:36:20 and 07:36:31, followed by an automated system override that unlocked the door.

Explanation: At 07:36:20, the user manually locked the front door. Immediately after (at 07:36:22), the door contact sensor triggered 'False' (indicating the door was opened or bypassed).

Explanation: The door contact returned to 'True' (closed) at 07:36:30, suggesting the intruder exited quickly or the door was reseated.

Explanation: Within 11 seconds of the manual lock, the system automatically unlocked the door at 07:36:31. This rapid sequence (Lock -> Open/Bypass -> Close -> Auto-Unlock) strongly suggests an intrusion event where the smart home logic interpreted a breach condition (or was triggered by the physical opening) to unlock the door, potentially allowing unauthorized access or indicating a sophisticated bypass.

Explanation: No occupancy sensors in the living room detected presence during this specific 11-second window, which is consistent with a quick flash entry/exfiltration rather than normal human movement.

[2026-06-09T07:36:30] front_door_contact | BooleanState.StateValue = True

Immediately review security camera footage for the front door covering the 07:36:00 - 07:37:00 timeframe.

Check motion sensor logs for the hallway/entrance area specifically between 07:36:20 and 07:36:35.

Investigate the configuration of the 'Auto' unlock logic to determine if it was correctly triggered by a door-open signal or if it represents a malfunction/exploit.

Temporarily disable automatic unlocking features until the cause is verified.

Standard overnight absence confirmed by multiple occupancy sensors reporting empty status across living room, bedroom, and bathroom between 00:00 and 01:30.

Door Lock State transition from 2 (Locked) to 1 (Unlocked) via Auto source

Time proximity between Bedroom Window Closing (22:10:20) and Front Door Auto Unlock (22:10:24)

Check raw logs for motion sensor activity in the hallway/entrance area immediately before and after the 07:36:20 - 07:36:31 window to see if someone entered and left quickly.

Verify the configuration of the 'Auto' unlock logic; determine what specific condition (e.g., temperature drop, geofence exit, timer) triggered the unlock at 07:36:31.

Cross-reference the timestamp of the bedroom window closing with the home's scheduled routines to confirm if this was a programmed action.

Check for any camera footage or additional IoT events (lights turning on/off) in the living room or entrance during the 07:36 timeframe.

Occupants were detected inside the home (Bedroom) while the front door was automatically locked and contact sensors indicated the door was closed/locked shortly after.

Explanation: Occupancy sensor at 23:01:05 confirmed a person was present in the Bedroom.

Explanation: At 23:01:14, the Front Door Contact sensor triggered (StateValue=True), indicating the door was engaged/closed.

Explanation: Immediately following (23:01:15), the lock executed an 'Auto' operation and locked (LockState=1).

Explanation: The sequence of Occupancy -> Door Close -> Auto Lock suggests the system locked out occupants who were still inside, or an intruder gained entry before the lock cycle completed.

Verify physical status of residents immediately to ensure safety.

Review mobile app geofence history to confirm if 'Auto' lock was intended based on user location.

Check for signs of forced entry or tampering on the front door.

Reset smart lock security settings and audit access logs.

Window covering status: Bedroom windows fully closed (100%) shortly before the auto-lock event, potentially indicating an attempt to conceal activity or secure the scene after an intrusion.

Check raw events between 18:32 and 23:01 for any sensor power loss, network disconnection, or unexpected reconnection.

Verify if 'OperationSource=Auto' corresponds to a geofencing trigger (e.g., mobile app location) and cross-reference with GPS history for this time period.

Inspect bedroom_window_contact_sensor logs around 23:01 to confirm if the window was actually opened/closed physically versus just the cover motor moving.

Review kitchen_activity logs to see if cooking or appliance usage occurred during the 18:32-23:01 gap.

Repeated lock operation failures followed by an alarm indicate a mechanical or electronic malfunction rather than a successful intrusion attempt.

Explanation: Evidence shows four consecutive 'LockOperationError' events from Source=3 between 02:24:00 and 02:24:40, indicating the device failed to respond to commands.

Explanation: This failure cluster was immediately followed by a 'DoorLockAlarm', confirming the system detected the malfunction event.

Explanation: Occupancy logs show all rooms were empty during this window (02:00-02:50), ruling out active human presence causing the errors; temperature data also remains consistent with an unoccupied house, further excluding fire or cooking risks.

Immediately inspect the front door lock mechanism for physical obstruction, ice accumulation, or battery depletion.

Replace the front door lock batteries if voltage is low, as repeated failed attempts can drain power and cause subsequent failures.

Test the lock manually to ensure it operates smoothly before resuming automatic scheduling.

Suspicious occupancy pattern showing complete house vacancy for extended periods during active hours, potentially indicating a sensor failure or an empty-house scenario if residents are present elsewhere.

The system logs indicate a standard sequence of residents leaving the home and locking the door, with no evidence of unauthorized entry or sensor failure.

Explanation: At 18:10:00, a manual lock operation occurred while bedroom occupancy was still '1', indicating the resident inside locked the door before exiting.

Explanation: At 18:10:02, the front door contact state changed to False (open), which is consistent with the door being unlocked momentarily after the manual lock command to allow exit, or the sensor registering the door opening as part of the egress process.

Explanation: Crucially, at 22:13:40, the front door contact returned to True (closed) and was immediately followed by an automatic lock event, confirming the door remained closed for over 12 hours without intrusion.

Explanation: Occupancy sensors show continuous presence in the bedroom throughout the night, proving the residence was not compromised.

[2026-06-01T22:13:40] front_door_contact | BooleanState.StateValue = True

No immediate action required; events are consistent with normal household activity.

Optional: Verify physical alignment of the door magnetic contact sensor if similar transient 'open' states occur frequently during closing sequences.

Check for any 'DoorLock.UnlockOperation' events or 'contact_sensor' state changes indicating the door remained open after the manual lock attempt.

Evidence indicates a potential break-in where an intruder entered via the bedroom window and exited by locking the front door from the outside while no occupants were detected inside.

Explanation: Occupancy sensors in all private rooms (bedroom, living room, bathroom) consistently reported '0' (empty) from midnight until 23:15:09 when occupancy briefly spiked to 1.

Explanation: At 23:15:15, the bedroom window was fully opened (status 10000), followed immediately at 23:15:18 by the front door contact triggering open (True).

Explanation: Crucially, the front door was locked via Auto-lock at 23:15:19 without any preceding motion or unlock event in the entrance hall, suggesting the lock was triggered from the exterior after the intruder had already vacated the interior.

[2026-06-13T23:15:09] bedroom_occupancy | OccupancySensing.Occupancy = 1 (First sign of presence)

[2026-06-13T23:15:15] bedroom_window | WindowCovering.CurrentPositionLiftPercent100ths = 10000 (Window opened)

[2026-06-13T23:15:18] front_door_contact | BooleanState.StateValue = True (Door opened)

[2026-06-13T23:15:19] front_door_lock | Event: LockOperation(LockOperationType=0, OperationSource=Auto) (Door locked automatically immediately after opening)

Dispatch security personnel to the residence immediately for on-site verification.

Check the physical condition of the bedroom window frame and the front door for signs of forced entry or external manipulation.

Review video surveillance feeds (if available) specifically for the bedroom area between 23:14 and 23:16.

Living room window also closed/opened (lift percent 0) earlier at 09:57:21, indicating potential tampering with multiple egress points.

If the resident was going out normally, there should be a motion event in the entrance hall or kitchen before the door locks, which is missing in the salient/focus counts relative to the timeline gap.

Resident left the house late at night (around 23:15), opened windows to ventilate before leaving, then secured the front door upon exiting.

Window covering changes often occur before departure for ventilation.

Door locking at 23:15:19 matches a typical bedtime/exiting time.

The lack of any occupancy detection from 00:00 onwards makes a standard 'waking up and leaving' pattern less likely unless the sensors are blind to the hallway or the resident left so quickly they weren't caught.

Opening a bedroom window *and* a living room window right before leaving seems excessive for routine ventilation unless cleaning air filters or preparing for extreme heat, but the timing (late night) is unusual for such tasks.

Temporal proximity of Bedroom Window Opening (23:15:15) and Front Door Locking (23:15:19) without intermediate human movement data.

Persistent zero occupancy readings across all private rooms (bedroom, bathroom, living room) from midnight onwards despite high activity counts elsewhere potentially implying ghost events or sensor failure, or true emptiness.

Check for 'OccupancySensor' trigger events in the Entrance Hallway specifically around 23:14-23:16 to see if someone walked through.

Verify the source of the 'front_door_lock' operation at 23:15:19 (App control vs. Physical handle turn vs. Auto-lock timer).

Cross-reference the 'window_covering' log at 09:57:21 with light sensors to confirm if curtains were actually moved or just a status report glitch.

Check temperature logs for sudden drops or spikes that might indicate HVAC shutdown due to window opening or intrusion.

Sequence of events at 22:04 indicates potential unauthorized entry involving bedroom window manipulation followed by immediate front door unlocking.

Explanation: Occupancy sensors show the house was empty (sleeping) until 02:30, ruling out residents being awake to open windows or doors.

Explanation: At 22:04:35, the bedroom window was opened to 100% while the house remained unoccupied in sensor logs.

Explanation: Only 6 seconds later at 22:04:41, the front door unlocked automatically ('Auto'), a sequence inconsistent with normal resident behavior and suggesting an automated bypass triggered by the intruder.

Explanation: The temporal proximity of the window opening and door unlock implies a coordinated action to facilitate entry.

No occupancy change recorded between 22:04 and 22:05

Immediately dispatch security personnel to the property for verification.

Review video feeds from cameras near the bedroom window and front door for timestamps around 22:04.

Contact homeowners to verify if they authorized any automation rules for window/door interaction.

The source code of the 'Auto' unlock event at 22:04 to determine if it was triggered by a sensor (e.g., motion, smoke) or a remote command.

Motion sensor logs for bedroom_window and entrance at 22:04 to see if movement preceded the window opening.

User authentication logs to verify if the 07:32 Auto-unlock was authorized.

History of 'WindowCovering' actuation commands to distinguish between user-controlled vs. automated rules.

The sequence of events (manual lock at 18:30 followed by auto-lock at 22:03) is consistent with a homeowner leaving during the day and returning to arm the security system in the evening, rather than an unauthorized entry.

Explanation: Occupancy sensors for all zones (kitchen, living_room, bathroom, bedroom) consistently report '0' from 12:00 onwards, confirming the house was empty after the manual lock at 18:30.

Explanation: The 'Auto' lock event at 22:03 occurred 3.5 hours after the manual lock; this timing aligns with the user returning home, checking the environment (opening curtains), and then arming the system via app/voice command, which is a standard routine.

Explanation: There is no evidence of forced entry, door opening/closing events between 18:30 and 22:03, or conflicting sensor data indicating occupancy when the house was reported empty.

[2026-06-24T12:00:00] kitchen_temp_sensor | ... OccupancySensing.Occupancy = 0 (and subsequent logs show continuous 0)

Review smart-home automation schedules to confirm if the window covering motor has a programmed schedule that triggers around 22:00.

Verify the source ID of the Auto-lock command against registered user devices to ensure it originates from a known controller.

Cross-reference bathroom_occupancy and kitchen_occupancy logs around 18:30 to confirm if anyone was present when the manual lock occurred.

Check if the window covering motor log shows a manual override or remote trigger vs. automatic schedule.

Evidence indicates a potential unauthorized entry where the house was locked from the inside at 18:17, followed by a rapid temperature spike and occupancy detection in the living room without any prior exit or re-entry motion data.

Explanation: Occupancy sensors reported '0' for all rooms from 12:00 to 18:00, indicating the house was empty during the day.

Explanation: At 18:17, a manual lock operation occurred while the front door contact sensor registered as closed (False), implying someone inside locked the door from the interior.

Explanation: Immediately following the lock (within 2 minutes), the kitchen temperature spiked drastically from ~235°C (scaled) to 2576, and the living room occupancy sensor flipped to '1', suggesting an intruder entered or staged the scene after the door was secured.

Explanation: The sequence of 'Lock from inside' -> 'Door Closed' -> 'Temp Spike/Occupancy' lacks any corresponding log entries for an initial exit earlier in the afternoon, pointing to a breach rather than a normal departure.

Household left around 12:00 PM (all rooms empty), returned later, and performed routine evening locking/unlocking via automation.

room_activity indicates significant activity in living_room and kitchen during earlier hours

Manual lock at 18:17 is inconsistent with typical departure patterns if no one was home; also, curtain fully closed at 21:50 while auto-lock occurred suggests possible staging for absence rather than return.

Manual lock operation on front door at 18:17 followed by auto-unlock at 21:50 without corresponding re-entry/exit motion data.

Complete lack of occupancy detection in all rooms between 12:00 and 14:22 despite high event counts in other log segments, suggesting potential sensor failure or staged vacating.

Check camera feeds or doorbell logs between 18:00–19:00 to see who performed the manual lock at 18:17.

Verify if any devices were actively used (e.g., dishwasher start, AC change) during 12:00–14:22 despite zero occupancy readings.

Cross-reference window coverings state history around 21:50 to confirm if curtains were manually adjusted or automatically set.

Inspect temperature patterns for anomalies that might indicate an unoccupied space being heated/cooled abnormally.

中等可信度警报，建议住户确认是否本人操作

The sequence of events indicates a standard evening routine where occupants manually locked the door and subsequently settled in the living room; the contact sensor reading 'False' (open) immediately after locking is consistent with the user closing the door from the inside to secure it.

Explanation: At 18:21:00, the front door lock was operated manually by UserIndex=1, followed immediately at 18:21:02 by a contact sensor state of False. In smart home logic, this transition (Lock -> Open/Closed) typically signifies the authorized user closing the door from the interior to engage the latch, rather than an intruder entering while the door is open.

Explanation: Subsequent logs show the entrance light turning on (18:21:08) and occupancy in the living room registering as 1 shortly after (18:21:15), confirming that legitimate occupants are present inside the home.

Explanation: A second manual lock operation occurred later at 20:31:00 with explicit UserIndex=1, further validating that the household member has control over the locks and the system is functioning normally without signs of unauthorized access or intrusion.

[2026-06-16T18:21:08] entrance_light | OnOff.OnOff = True

Continue normal monitoring; no immediate intervention required.

Verify the specific firmware version of the door lock and contact sensor to ensure the 'False' state upon internal closure is documented in device manuals, though current evidence strongly supports normal operation.

Check raw state history for front_door_contact between T18:21:00 and T18:21:15 to determine if the door remained open or briefly opened/closed.

Verify if any motion was detected immediately outside the entrance zone during the interval T18:21:00 - T18:21:15.

Cross-reference UserIndex=1 with known household members to confirm if the manual lock at 18:21:00 was authorized.

No anomalous behavior detected; prolonged bathroom occupancy is consistent with normal usage patterns and supported by stable environmental sensor data.

Explanation: The provided raw log excerpt only covers the period from 11:55 to 14:55 (approx. 3 hours), whereas Hypothesis H1 requires evidence of events occurring at 21:46 (9 PM) to support a security threat.

Explanation: Within the available log window, the bathroom occupancy signal remains active ('1') continuously without any intervening '0' states, which contradicts the hypothesis that the resident left the room before the night-time events.

Explanation: Environmental sensors in the living room and kitchen show natural temperature fluctuations typical of residential HVAC cycles, indicating no signs of forced entry (e.g., rapid heating/cooling) or equipment malfunction.

Explanation: Without data from the 21:46 time slot, the correlation between the morning bathroom session and potential night-time locking cannot be established, rendering the anomaly claim unsupported by the current evidence packet.

Raw log timestamps range from 11:55 to 14:55, missing the critical 21:46 event window entirely.

Bathroom occupancy value remains constant at 1 throughout the entire provided dataset, suggesting continuous presence rather than intermittent activity.

Temperature readings in adjacent rooms (Living Room/Kitchen) exhibit gradual, realistic drifts (25°C -> 24°C range) consistent with normal home climate dynamics.

Retrieve and analyze the full 12-hour log specifically focusing on the 18:00-23:00 window to verify the existence and source of the front door lock and window covering events.

Cross-reference the timestamp of the alleged 'Auto' lock trigger with homeowner device history to determine if it was a scheduled routine or an unexpected automated response.

Gap analysis: Significant time elapsed between last known bathroom occupancy (12:45) and the suspicious night-time actions (21:46), raising questions about unmonitored intermediate activities.

Source anomaly: Front door lock operation source is 'Auto' shortly after a 'Manual' lock, which may indicate an automated security system trigger that could be misconfigured or triggered by an external factor.

Raw timestamps and device IDs for the period between 12:45 and 21:46 to check for any missed motion detection in living_room or kitchen.

Specific value of 'WindowCovering.CurrentPositionLiftPercent100ths' before and after the change to confirm if it was fully closed or just stopped moving.

History of 'front_door_lock' operations to determine if 'OperationSource=Auto' is standard behavior for this smart home setup or a new deviation.

Correlation with utility data (electricity/gas) during the 11:55-12:45 bathroom block to see if high-load appliances were running consistent with normal usage.
