The engine behind Studio coming
Saggio is the engine behind Studio — the layer that reads your training and recovery data and produces the honest daily call. It isn’t a separate app you install; it’s what makes the answer trustworthy.
Part of Studio — nothing separate to install.
You meet Saggio through Studio. Here’s what it stands for.
Your readiness is scored against your personal rolling baseline — not a population average.
Recovery signals are scored with robust z-scores so a single odd night doesn’t swing the call. HRV is read as a 60-day baseline, smoothed against a 7-day rolling average, using SDNN honestly.
HRV method after Shaffer & Ginsberg (2017).On a fresh account it says it’s still building your baseline, instead of faking precision.
Estimates are labelled “≈”, and the daily call carries its own confidence. The recovery-deviation cue is a non-medical attention signal, never an illness claim.
See the honesty page for the full model list.A non-medical attention signal. When several recovery signals drift off your baseline together for two or more days, Saggio flags it and Studio suggests an easier day — it does not detect, diagnose or predict illness. Wrist temperature is a deviation from your baseline, never a fever reading. The deeper internals live in the app, kept deliberately minimal here.
