I did a fondo and the Edge gave me an increase in FTP from 237 to 268. 2 days later, I did a street ride and the Edge lowered my ftp to 248.
Why did it take so many rides to get the device to increase the FTP? And then it takes only 1 ride and the Edge can decrease the FTP? After recovering from the Fondo, I thought I would be even stronger? I did the latest street ride (the one that lowered my FTP) in my fastest time! I used a Power Guide that said I needed to average 80% of my FTP to beat my best time on the course. I averaged 268W (101% of my FTP ) on the ride for 23 miles and my FTP drops to 248. I'm not understanding this at all.
Does previous data from my Fenix 6 interfere somehow?
Thanks,
