HRV-Based Recovery & Readiness Score
Scores today’s recovery 0-100 from morning HRV (rMSSD/SDNN) and resting heart rate z-scores against your own rolling baseline, blended with last night’s sleep and yesterday’s session RPE — with a green/amber/red tier, meaningful-change (0.5 SD) detection, baseline noise (CV) check, and an intensity-ceiling training recommendation.
