FTP wrong race detection?

I made a run at an average of 217W in 80minutes, so the FTP auto-update should have detected at least 217W, but instead zwift has updated it to 213W, what happened here?

I assume because zwift uses a 20 minute effort not a 60 minute effort to estimate FTP and the 95% rule isn’t perfect.

You can manually change your FTP if you want.

ahhhh, you’re right!
