Recovering from surgery, have to take 6 weeks off the bike. I looked at my progression levels today and they seemed lower than a week ago right before I stopped training. Does AI adjust the progression levels to account for time off the bike ?
Short answer: yes.
They also adjust if you don’t target certain areas. For example - Your VO2 level is 7.0. If you do nothing but Endurance and Tempo for a few weeks, you’ll see that number creep down as you see Z2and3 creep up.
OK thanks. Not really important, I have no illusions about the loss of fitness over this time off. Will start back slowly, ramp test and then build up again.

Some of these levels decline unrealistically fast IMO.
If I have a while with no sweetspot, my level will drop off fast from 10 to about a 6, but I have comfortably gone on to do not recommended level 11 or 12 workouts. Interested to know if decay is standard or athlete specific, but for me it’s just not realistic 
I’m about to restart after 9 days of no riding due to a virus (not Covid).
Be interesting to see what the PLs are and I will also re-do a ramp test estimate using AT detection so will be really interesting to see how much the AI estimates my FTP has dropped (I’m gonna guess at about 15 watts (6% ish) in that time.
So did the FTP detection ramp test today.
AI dropped my FTP to 298 (from 306) which is only about a 2.5% drop.
That’s less of a decay than I imagined. I wonder if I will find the workouts a struggle or not.
Only one way to find out
