For me, AT has been a game changer. For you? I couldn’t say.
I tried using AI FTP today after taking a six week break (new dad…). Surprisingly AI FTP told me my FTP had increased by a few percent. I declined the adjustment since I highly doubted that this was correct. After doing a trainnow workout (or trying anyway) with my old FTP I can confirm that my FTP has indeed not increased.
I tried using AI FTP again to see if I get a more reasonable number, but now I can’t use it for 14 days…
I think to remember from the podcast that AI FTP should account for training breaks, or was that only for the progression levels (which have decreased).
Any ideas how to proceed here?

I used this today…got 250 up from 230. Pretty happy, considering I was dreading a test (always am) I like that it takes the outdoor unstructured rides into consideration. Sometimes those are pretty tough in their own right. So all contribute, keep up the good work team.
My most recent FTP detection on March 29, 2022 put me at 220. Due to travel, I have not been able to train as much as usual, but on two group rides in last two weeks, my estimated FTP (intervals.icu) was 244 and 243, respectively.,based on 19 minutes at 257 Watts during the ride. Today, I tried FTP detection and it suggested 219 as my new FTP. I’m not sure how detection works, but I feel like my FTP is conservatively well above 220. What’s your take?
@DavidWms , do you use the same power meter for outside rides as well as inside rides? When you got your original March 29, 2022 AI FTP of 220 did you find it unusual based on your TR workouts? I assume if your FTP is truly off by 20+ watts you would be finding your TR workouts fairly “easy”, no? If not, seems something is not quite lining up.

I think AI-FTPD uses mostly completed workouts and power under/over target. Not strictly power for x-duration.

Inside, I use Kickr, which is a few watts lower than my Assiamo PM outside. Honestly, my actual TR’s workouts have been few recently due to travel and family issues, as well as warmer outside temps. I do convert my outside riders to “equivalent” TR workouts using TSS, IF, and time, so I hoped I would get credit today for the stronger power on my outdoor rides. An FTP of 244 would be a PR for me: 13 points higher than my best ever FTP (and at almost 70 y/o!) I’ve raised a support ticket but am inclined to manually increase my FTP to 232 (half-way in between) and see how that goes.

I think WL V2 will help with your situation, but until then you’re probably not quite getting full credit in terms of the FTP detection. Though you’ll be getting AI adaptations etc.
Congratulations on your improvements

What is WL V2, if I may ask. Thanks. I’ve also been doing polarized plan, which doesn’t work with AI FTP as I understand.

It is “Workout Levels Version 2.0” as mentioned by Ivy here in several comments. That is the pending update to the overall TR system of evaluating completed workouts.
-
It is aimed at covering all workouts in better ways, but specifically improving / adding the ability for AT to properly leverage data from our outside rides to set our Progression Levels, which drive changes by AT to our training plans on the calendar.

TR support said I could manually update FTP and then do the Marion workout to see if I can handle it. I’ve conservatively adjusted from 220 to 235 and will attempt that workout to test accuracy.

For TrainerRoad->Profile->TSS Estimation.
Estimating the power isn’t the problem - TSS estimation implies calculating the approximate power. For detecting FTP increases, both methods would just have to guess that the TSS increase was productive to overall FTP evolution. But apparently TR doesn’t actually do that yet for unmatched workouts - and that’s the real problem here.
Another anecdote:
I just finished SSLV Base 1 (MTB marathon) and FTP-Detection gave me a 1W bump, 285 → 286.
In the few months before this phase my FTP was steadily rising from 271-285.
I’m a little surprised since I’ve been doing 9.5-10.0 Sweet Spot workouts, and adding 3+ hour endurance/tempo rides most Saturdays (I call it “Low Volume+”) 
Might try my own ramp test and see what happens.

My AI-FTPD has gone 328->324->320W whilst I was still cruising through the 10+ SSBHV workouts at 328W setting.
My suspicion is that the ML is just getting more, and more refined and being more conservative/getting closer to LT. I only say that as there’s no reason I’d have had a decline otherwise as far as I can tell.
If you’re getting increases still I’d still take confidence from that.
(I have had two weeks essentially off now so the FTP setting is definitely down, but the changes were suggested prior)

At this point I’m pretty convinced the AI ftp setection isn’t working properly with high progression levels. I had a 2w ftp bump, but my progression levels barely dropped at all. So I start my new phase with 7+ and end with 9+ progression levels. Once I get this high, I habe to mark workouts as hard and very hard and I suspect this again leads to a very small bump in ftp and a minor drop in progression levels. Repeat etc.
I don’t get why it has to be that way. The old plans very rarely had workouts with a higher progression levels as 7 and were still considered productive.
- Have you contacted support with these issues & questions?
- If so, what have they told you about the status here?

Tbh, why bother. Everytime I raised my concerns with progression levels and AI ftp detection the answer was basically “working as intended”
@pnzr I’m a little late to this particular conversation but I’m not sure how much you think your progression levels should change for a 2w change in FTP? 2w is less than the difference between a good and a bad day. It probably registers less than 0.1 of a change in progression.
I’ve just had similar, a 3watt increase in FTP and whilst I thought it might knock my progression levels back a bit and give me some easier workouts for a week or so, it doesn’t actually look like it has changed anything.
Which if I’m being honest… 3watts shouldn’t make or break a session and the sessions should still be about right (progression levels the same as before)

I agree, but if 7+ progression levels without failes workouts don’t result in an bigger ftp bump, than something is wrong with the system.
