Week 2 was a clean recovery week. Compared with the Week 0 baseline and the Week 1 active comparison, every score moved above baseline, every autonomic marker improved, REM normalized, Sleep Stress dropped below baseline for the first time, and the two collapse nights that defined Week 1 disappeared. Sleepgenic classifies Week 2 as adaptation conversion — the body absorbed the Week 1 stimulus pressure and converted it into a higher physiological floor.
Week 2 is the second active Sleepgenic Weekly Report. The purpose of this report is to compare Week 2 against both the Week 0 baseline and the Week 1 active week, and to determine whether the adaptation pressure observed in Week 1 produced recovery, regression, or further strain.
Across Week 2, the average Overall Score was 70.7, compared with Week 1's 60.2 and the baseline median of 67.5 — an increase of 10.5 points versus Week 1 and 3.2 points versus baseline. The Quality Score averaged 77.0, up from 69.5 in Week 1 and above the baseline median of 74.0. The Duration Score averaged 76.9, up from 66.5 in Week 1 and above the baseline median of 72.0.
The strongest score-layer move came from the Recovery Score, which averaged 78.6, compared with 62.0 in Week 1 — a swing of 16.6 points week-over-week. This is the same score that posted the largest Week 1 deficit, and it is now leading the rebound. Recovery Score is now above the baseline median of 75.5 as well.
The physiology layer confirms that the score-layer recovery is real and not surface-level. HRV averaged 43.3 ms, compared with 37.2 ms in Week 1 and the baseline median of 35.0 ms — an increase of 6.1 ms versus Week 1 and 8.3 ms above baseline. This is the strongest autonomic signal in the active dataset to date.
Resting heart rate averaged 60.6 bpm, compared with 63.2 bpm in Week 1 and the baseline median of 65.0 bpm — a drop of 2.6 bpm versus Week 1 and 4.4 bpm below baseline.
REM sleep averaged 1.10 hours, compared with 0.80 hours in Week 1 and the baseline median of 0.81 hours. This is the cleanest structural improvement of the week. Week 1's flat REM was the unresolved item from the prior report; Week 2 resolved it.
Deep sleep averaged 1.38 hours, slightly below Week 1's 1.46 hours but still above the baseline median of 1.25 hours. Deep sleep stayed elevated while REM caught up — the architecture rebalanced rather than traded one structure for another.
Total sleep averaged 6.01 hours, recovering from Week 1's 5.75 hours and matching the baseline median of 5.99 hours.
Sleep Stress averaged 15.8, compared with 20.4 in Week 1 and the baseline median of 17.2 — a decrease of 4.6 points versus Week 1 and 1.4 points below baseline. This is the metric that confirms Week 2 is genuine recovery and not improved scoring on top of unresolved load.
Restless moments averaged 42.6, essentially flat to Week 1's 40.7 and slightly below the baseline level of 44.0. SpO2 averaged 96.0%, stable.
Week 2 followed the same stimulus calendar as Week 1 — Rest, Summit, Recovery, Recovery, Rucking, Run, Walk — but the response pattern inverted. The two nights that collapsed under load in Week 1 are the two nights showing the largest improvements in Week 2.
The Summit night on 4/26/2026 posted an Overall Score of 78 with Recovery Score of 75, REM of 1.33 hours, and Sleep Stress of 17.6 — compared with the Week 1 Summit night which posted 49 despite 8.42 hours of sleep. Same stimulus, materially better restoration.
The Run night on 4/30/2026 posted an Overall Score of 62 with Duration Score of 100, total sleep of 7.15 hours, and HRV of 45 ms — compared with the Week 1 Run night which collapsed to 41 with Recovery Score of 29 and only 3.60 hours of sleep. Run remains the weakest stimulus response across both weeks, but the collapse pattern broke.
The cleanest night of the active dataset to date came on 4/28/2026 after the second Recovery day: Overall Score 82, Recovery Score 87, Duration Score 89, HRV 46 ms, resting heart rate 59 bpm, Sleep Stress 13.2, REM 1.35 hours, total sleep 6.82 hours. This night arguably exceeds the Week 1 standout night of 4/20/2026.
The only weak Week 2 night was the Walk night on 5/1/2026, with an Overall Score of 52, total sleep of 4.53 hours, and Duration Score of 53. Notable but not a collapse — the lowest Week 2 score (52) is still 11 points above the lowest Week 1 score (41).
The two-week running profile now becomes the operating reference layer for Week 3 and beyond. The running average for Overall Score is 65.4, Quality 73.3, Recovery 70.3, Duration 71.7. Deep sleep runs at 1.42 hours, REM at 0.95 hours, total sleep at 5.88 hours. HRV runs at 40.2 ms, 5.2 ms above the baseline median. Resting heart rate runs at 61.9 bpm, 3.1 bpm below the baseline median. Sleep Stress runs at 18.1 and SpO2 at 95.8%.
The autonomic system is trending toward a higher recovery setpoint, not just bouncing within baseline range.
Sleepgenic classifies Week 2 as adaptation conversion. Week 1 absorbed pressure with mixed signals — score layer down, physiology layer mostly up, stress elevated. Week 2 converted that pressure into a higher physiological floor with all three layers aligned. HRV broke above baseline, Sleep Stress dropped below baseline, REM normalized, and the collapse nights disappeared.
The watch item for Week 3 is whether the elevated HRV setpoint holds under another full stimulus cycle, or whether it regresses toward baseline once the recovery accumulation stops. The secondary watch item is the Run-night response, which improved from 41 to 62 week-over-week but remains the slowest-converting stimulus and the most likely place a regression would surface first.
