dataset spine.

Week 12

Week 12 recorded a full seven-night recovery rebound after the Triple Summit trip. Overall Score rose to 74.4, Recovery Score to 80.3, REM to 1.21 hours, total sleep to 7.55 hours, resting heart rate improved to 63.1 bpm, Sleep Stress fell to 15.8, and SpO2 returned to 95.4%. HRV remained slightly below baseline at 33.6 ms and restlessness stayed elevated. Sleepgenic classifies Week 12 as systemic rebound with residual autonomic and fragmentation lag.

Week 11

Week 11 captured the Wheeler Peak and return-travel phase with only four of seven nights observed. Total sleep averaged 8.67 hours and Duration Score 84.0, yet Overall Score averaged 50.3, Recovery Score 52.8, resting heart rate 70.0 bpm, and Sleep Stress 27.7. The post-Wheeler night showed 8.85 hours of sleep but a Recovery Score of 12. Sleepgenic classifies Week 11 as the accumulated-load trough under incomplete coverage, with early recovery appearing late in the week.

Week 10

Week 10 produced the clearest duration–recovery divergence in the dataset. Six of seven nights were recorded during the Mount Elbert and Pikes Peak segment of the Triple Summit trip. Total sleep averaged 7.52 hours and Duration Score 81.2, yet Overall Score fell to 53.5, Recovery Score to 37.0, resting heart rate rose to 72.7 bpm, Sleep Stress to 34.4, and SpO2 fell to 92.8%. Sleepgenic classifies Week 10 as high-altitude accumulated strain: more sleep time did not equal restored physiology.

Week 9

Week 9 captured the transition into the Triple Summit road trip with incomplete coverage. Five of seven nights were recorded. Overall Score fell to 61.0, HRV to 32.4 ms, resting heart rate rose to 64.2 bpm, Sleep Stress rose to 21.2, and SpO2 averaged 94.0%. A zero-REM night preceded a strong rebound the following night. Sleepgenic classifies Week 9 as transition strain under incomplete observation — a directional signal, not a complete weekly verdict.

Week 8

Week 8 regressed toward baseline at the score layer without showing broad physiological deterioration. Overall Score averaged 68.1, nearly matching the 67.5 baseline, while Recovery Score reached 85.9, HRV rose to 40.9 ms, resting heart rate fell to 59.4 bpm, and Sleep Stress improved to 14.1. One 3.18-hour night pulled the weekly score downward, but the underlying recovery signals remained strong. Sleepgenic classifies Week 8 as score volatility with physiological strength — normalization after the Week 7 peak, not a renewed strain cycle.

Week 7

Week 7 consolidated the recovery into the strongest week of the run. The average Overall Score reached 75.6 — the highest weekly score recorded, above baseline and above the previous best in Week 2. REM held above baseline at 0.94 hours, confirming the Week 6 recovery was durable rather than a single strong week. HRV recovered off its Week 6 dip, narrowing the divergence that week had opened. After a complete strain-and-recovery cycle, the body did not simply return to baseline — it converted the cycle into a higher state. Sleepgenic classifies Week 7 as adaptation conversion: the supercompensation payoff of the preceding strain.

Week 6

Week 6 is where the recovery completed. REM sleep returned to 1.00 hours — above the 0.81-hour baseline for the first time since Week 2 — confirming that the Week 4 collapse was a recoverable strain response, not a persistent block. Overall Score rose to 71.3, above baseline. The week also overturned a hypothesis: the Week 5 report flagged the Summit night as a concentrating strain point, but in Week 6 the Summit night scored 83, the week's best. The high-load-strain reading did not survive contact with a recovered week. Sleepgenic classifies Week 6 as completed reversal — the strain cycle closed, and the body returned to and slightly above its baseline.

Week 5

Week 5 answered the question Week 4 left open: REM partially recovered. After collapsing to 0.17 hours in Week 4, REM rebuilt to 0.62 hours — a real reversal of the three-week decline, but still short of the 0.81-hour baseline. Overall Score rose to 64.3 and autonomic markers held steady. But against an unchanged training calendar, a sharper signal emerged: the Summit night has become the weakest night of the week, scoring 38 where it once scored 78. Sleepgenic classifies Week 5 as partial reversal with concentrating high-load strain — the overall trajectory is repairing, but the body is no longer absorbing its hardest day.

Week 4

Week 4 is where the strain became visible. The thinning sleep architecture flagged in Week 3 did not recover — it deepened. REM sleep nearly disappeared, averaging just 0.17 hours across the week, and Sleep Stress spiked to its highest level of the run. The Overall Score fell to 52.1, dragged down by two genuine failure nights. But Recovery Score held and resting heart rate stayed moderate, so this was not a total breakdown. Sleepgenic classifies Week 4 as strain surfacing — the week the latent strain from Week 3 broke through into the score layer.

Week 3

Week 3 looked stable on the surface — Overall Score held near Week 2, and Recovery Score reached its highest level of the run so far. But the physiological layer told a quieter, less reassuring story. REM sleep fell sharply, deep sleep dropped below one hour on average, and HRV went largely unrecorded. The scores said steady; the architecture said thinning. Sleepgenic classifies Week 3 as latent strain under stable scores — a week where the headline numbers held while the underlying sleep structure weakened.

Week 2

Week 2 confirms adaptation conversion. Every score moved above both Week 1 and the Week 0 baseline, the score layer and physiology layer realigned for the first time in the active dataset, HRV broke above baseline, Sleep Stress dropped below baseline, REM normalized, and the collapse nights from Week 1 disappeared. The pressure absorbed during Week 1 has been converted into a higher physiological floor.

Week 1

Week 1 showed a clear split between score-level decline and physiological resilience. Compared with the Week 0 baseline, Overall Score, Quality Score, Recovery Score, Duration Score, total sleep, and sleep stress all moved in the wrong direction. But deep sleep, HRV, resting heart rate, and restless moments improved versus baseline. This suggests the body was under adaptation pressure rather than simple sleep deterioration.

Historical baseline medians from November 23, 2025 through April 17, 2026, reconciled to 145 calendar rows: 80 scored nights, one time-only partial record, and 64 explicit missing nights. The medians remain the fixed historical reference; rolling 28-day personal baselines now support ongoing interpretation.
