The vast majority of my riding is outdoors, tracked using a Wahoo Elemnt and synced directly to TR (not via Strava).
I’ve noticed that the AI FTP reported each month is suspiciously static and is reporting an identical FTP month on month.
The reason I’m sceptical: I noticed a drop in form during the summer - not massive, but enough to mean my 20min TT effort was no longer sustainable. TR has, in past years, picked up on this.
Has something changed? Now that we’re entering Autumn/Winter I’ll be getting more time on the turbo, which may fix it - but I expect my zones will be out for a while.
The AI FTP has always seemed to be close enough that I could use it as a gauge.
