Bio signal
Heart-rate variability, resting heart rate, sleep quality, recovery. Data she already has — connected, not duplicated — so it composes into the same readiness call as everything else.
What it measures
The gold-standard recovery metric. Higher HRV means her nervous system is ready to train; a sudden drop means it isn't — regardless of how she feels.
The simplest trend that matters. When resting heart rate creeps up over three days, her body is fighting something — even if she doesn't know it yet.
Hours in bed, time asleep, restfulness. The objective side of the sleep story, measured by the device on her wrist.
A composite score that synthesizes the biological signals into one number: is her body ready for what today's practice demands?
Recovery trends over time. When her HRV drops and her resting heart rate rises, the readiness call adjusts — the right call, clear before she feels it.
Nothing extra. If she wears an Apple Watch, Garmin, or Whoop, the data flows in automatically.
How she feels is one fragment. What her body measures is another. When they agree, confidence is high. When they disagree — she says she's fine but her HRV says otherwise — that's when composing the full picture earns its keep.
