My FTP jumped ~ 130 watts following a ride I uploaded yesterday (sweet spot interval workout). There’s no way I could hold the new FTP for more than a couple of minutes, certainly nothing close to an hour. Also uploaded the ride to TrainingPeaks and WKO and am not seeing anything that would indicate bad data. Has anyone else seen this? Might there have been a change to the app yesterday?
