HRV (Heart Rate Variability / RMSSD) Tracker Excel — Personal Baseline, Readiness Score & Trigger Analysis

The Framingham Heart Study found that people in the lowest quartile of HRV had 32% higher all-cause mortality than those with higher HRV, independent of other risk factors. This tracker logs your daily RMSSD reading, calculates YOUR personal rolling baseline (since HRV is highly individual), and gives you a daily readiness signal comparing today's reading against your own trend -- plus automatically analyzes which factors (alcohol, hard training, stress) actually move your HRV up or down.
