Measured against you, not a population average.
HRV, resting heart rate, sleep and sleep consistency, weighted and compared against your own baseline — not a chart built for someone else's body.
Strain is a real formula
Banister TRIMP over real heart rate samples, 0 to 21, not a step count wearing a fitness label.
Confidence, stated plainly
No data, rough, fair or solid — and which inputs were missing, named directly. A day the Watch never saw reports as unknown, never as a silent zero.
Your own median, your own spread
The same HRV reading means something different for two different people; this is scored against where YOUR number usually sits, not a fixed threshold everyone shares.
What you did yesterday sets what today can carry.
Recovery → Fitness
This morning's recovery score is what sets today's strain target — a real number, not a plan written a month ago that doesn't know how you slept.
Sleep → Recovery
A short or broken night shows up here directly, in the same confidence label the score already carries.
