Review an estimate before applying it

Open Account settings → Power zones to inspect cycling eFTP. The estimate uses qualified power efforts with source context and provides a reason when evidence is insufficient. It does not silently replace your FTP. Estimated FTP methodology describes the duration evidence and fallback models.

Check recency and agreement

The evidence window reaches back 180 days; evidence older than 90 days is stale. The model examines sustained power around five, ten, twenty and thirty minutes, prefers suitable multi-duration evidence and uses constrained fallback estimates where necessary. Source and indoor/outdoor differences matter; combining unlike power meters can disguise disagreement.

Apply only the estimate you accept

Compare the estimate with the configured FTP and its history, then use the explicit apply action if you want the supported threshold updated. Keeping the current threshold is a valid outcome. This is cycling evidence, not proof of a native iOS feature, a laboratory threshold test or automatic coaching.
