Readiness scores, and when to trust them

A readiness score is a summary, and every summary throws information away. It is assembled from resting heart rate, HRV, body temperature, sleep and recent activity, weighted against your own recent history — which means a single number can drop for reasons that matter a great deal or not at all, and the score itself will not tell you which.

The posts here take the score apart: what feeds it, why it lags a bad night, why it sometimes reads low when you feel fine, and what to do when your body and your ring disagree. The short version is that the score is a prompt to look closer, not a verdict on the day — and treating it as a verdict is how people end up managing the number instead of their health.
