Sleep — 2026-09-10
8h 26min · 00:10→08:56 · REM: 9% · Deep: 39% · HRV: 123 · Resting HR: 49 · Woke: 2× · Score: 91/100
Score 91 — new best in the log (beats 90 from Jul 20), better than 99% of users. No narrative given for the night. Watch advice: woke 2×, slightly above average; suggested meditating before bed.
Interpretation: The highest-scoring night on record, and it was built on deep sleep, not on duration or timing. Deep 39% (3h 15min) at 95-point continuity is the heaviest repair share since Sep 5, light 52% sits normal for the first time in three nights, and deep continuity 95 is the cleanest of the week. The shape is unmistakably repair-first: the body spent the night on tissue/immune work and shorted dreaming to pay for it — REM 9% (48 min) is the second consecutive night under 10% (Sep 8: 7%), which is still the Sep 7 crash-night (32ms, ~4h) being worked off rather than a new problem.
HRV 123ms lands high-normal, third night of the settle: 145 → 127 → 123. That is not a recovery failure — it's the bedtime ceiling. The two nights at 145 (Sep 2, Sep 8) both went to bed pre-midnight (23:50 / 22:59); Sep 9 and Sep 10 both went to bed at ~00:10–00:25 and both landed in the 120s. Same story the scores don't capture: a late bedtime costs ~20 ms of HRV but, with 8h26 in bed, it doesn't dent the score at all. Resting HR 49 and SpO₂ 98% close it out — this is a genuinely recovered base.
(Curiosity, not signal: 00:10→08:56 is the exact clock of Sleep/2026-07-27 — same bedtime, same rise time, eight weeks apart.)
