You learnt the wrong lesson. Ramp test is a bad estimator of FTP. I’d bet money the AI is way better….If you want to do an assessment, go ahead and rip 30-40min hard. Or at a minimum do the Coggan protocol, for the latter don’t forget to go ALL OUT for 5 min!
agree to disagree. I’ve done both ramp tests and 20 minute test and they always align for me.
Maybe (anaerobic contribution) they both overestimate your FTP? 
Now that it has been a couple of weeks with your new ftp, how are you doing with the workouts? Where are you in a training plan also? You must have felt like superman before deciding to do an actual ramp test.
Let us know if AI FTP was way off the mark for you.
Good question. It took a bit of trial and error to find the right progression levels, because at first they were waaaaay too low (like level 1!). I hit the mark perfectly with the first threshold interval, picked one slightly too challenging (but doable) for a 90 minute sweet spot, and then aimed a bit low for the following VO2 max workout. But nothing that the trainerroad algorithm can’t deal with
So generally, my fitness has handled the change well.
What hasn’t handled the change well: my knees. One knee (the “problem” knee) had a flare up of patella-femoral pain. In retrospect, it would have been better to increment upwards the upwards change (in total 26 watts) over the span of a month. I’m now holding back and doing some endurance and tempo workouts until the soreness subsides.
