Just finished an activity. Got a breakthrough and my peak power went up.
Something unexpected happened though, the fitness signature on my “home” page doesn’t match the breakthrough value that I just achieved. It’s about 50W higher (just got 1281 W breakthrough, and fitness signature shows 1324 W on the home screen).
If I look at the “power duration” plot in the activity the “fitness signature for this activity” and “current fitness signature” don’t match. This is unexpected because I literally just finished the activity.
What am I missing? Is the “current fitness signature” taking into account recovery that hasn’t happened yet?
