Analysis
This is a textbook recovery night. 8h 33min of sleep with HRV back at 116ms — solidly in the sober baseline range (110-135ms). Deep sleep at 31% (2h 40min of actual deep sleep) is excellent and well above the Jul 15 sleep (23%, only 1h 21min). Resting HR at 52 is back to normal range.
The only minor flag is light sleep at 56% — barely above the 55% reference. Given the deep sleep was so strong, this isn't concerning. The 2 wake-ups persist (consistent pattern across most nights) but don't seem to impact overall recovery quality.
This is the polar opposite of the Jul 14→15 sleep (5h 52min · HRV 93 · Score 72) — whatever you did differently between these two nights, it worked. Three days of recovery between runs may have helped as well.
Run impact: Running on full recovery showed: 2.01 km at 6'08" pace with 147 bpm avg and VO₂Max bumping to 42. Clean, efficient output — exactly what proper sleep enables.
