Sleep
Total time in bed is the least interesting number here. What predicts recovery is the restorative fraction, the regularity of your schedule, and whether you are clearing the need your body has already accumulated.

Stages stack deepest-first and share one hue — depth reads as darkness. The stepped line is what WHOOP calculated you needed that night.
How far each night fell short of its need. Debt compounds — it is not cleared by one long lie-in.
Consistency is the most controllable input to sleep quality, and usually buys more than extra time in bed.
Correlation of 0.28 across 90 nights — sleep performance explains about 8% of the variation in your recovery score.

You have averaged 7h 36m asleep against a need of 8h 08m. Debt is repaid at roughly an extra hour a night — a single long weekend lie-in does not clear it.
