Physiologically, 1 or 2 watts isn’t going to change the stress or adaptation. I’d even argue that 10 watts is likely to not change it much either. If your FTP is really 350 but you have it set to 400, that’s probably not great, but if it’s 350 and you only have it set to 340, I don’t see an issue. Quite frankly, my 20’ power can vary 10-20 watts in just one week depending on fatigue and training, and it can vary 30+ watts just over a long 5 hour ride. Trying to set it within a few watts is the definition of futile.

If there was an “Automatically Accept AIFTP results” option (similar to the Automatically Accept Adaptations option), I would enable it.

The problem also turns up another way - you have to go and update your new diminishing change everywhere - Garmin, TP, Zwift etc. Too many places with no sync, easy to forget some.

Lol, TR must of heard me. After months of 2-3w increase offers which I turned down, last night they offered me 5w which I accepted. Maybe its too small too but its a reasonable amount of my small FTP and what I’ve always said I accept as a changing step (5w increments)

For me a win is a win, I take the small changes.
I just got a small bump of 4 watts on my last AI FTP.
I took it as if I had to repeat a class in school.
I completed all the previous workout but didn’t feel like I got stronger so I was cool with the 4 watts bump.
This did drop PL but not by much and the new workouts that TR gave me where at a higher level so in the end I don’t feel like it was a waste but more like fine tuning.
Also 230 just looks better than 226.
Why wouldn’t you want TraininerRoad to have the best chance of giving you its best shot?

It depends if it’s just a few watts up or down. Seriously, if it’s just 1-3 watts decrease, I typically don’t accept. But if it’s 1-3 increase, I accept it. It’s probably not the best practice.
No I don’t turn down the changes from AI FTP detection.
I’m paying for the TR system and I’ll follow it.
If I am not happy with a PL because I’m feeling great or bad on a given day I will adjust the workout.
I’ve had more success with less manual intervention.

Today’s AIFTP detection, which I accepted of course, was 0%
I wasn’t sure what to expect this time. Most of the work I have done since the last one has been based on the “fatmax / Steve Neal” stuff mentioned in other threads on the forum. Spruce +3 has featured a lot on the calendar.
I added a few sprint workouts across the period too, but there has been no threshold and just one VO2 that I didn’t complete.
So flat it was. Onto the next one.

After my first week of build 2, AIFTP proposed a 1.3% increase today that I accepted. Equaling an all-time high for me at 56 with a month of build yet to go, so pretty pleased. And based on a couple recent efforts, I think it’s possibly still ~5w low, but I generally prefer to be undershooting things a bit rather than overshooting.

I accept them all. It’s just number that goes into a calculation. I don’t see a reason to deny any level of granularity in that.

I also turn them down because it slightly bumps down the progression levels and then you repeat the same workout. I’d rather increase time in zone with a higher progression level than slightly bump the output.

I declined a 1% decline but accepted a 1.5% increase recently. Logic was that I wasn’t interested in making my workouts easier but was interested in taking on more challenging workouts even if small in the increments. I think if the reduction would’ve been more than 2-3% I would’ve accepted it, but I’m new to TR, didn’t feel I had enough time to confidently feel like the reduction was totally valid, and again, wanted to make sure the workouts stayed as challenging as they could be.
After reading replies, I decided that what the heck, I’d accept whatever the next AI FTP suggestion was, no matter how I felt about it. Today it bumped me from 197 to 201. For whatever reason, I still feel weird about accepting FTP increases (while still being excited that I’ve been steadily ramping up my progression levels) but whatever. I guess a 2% increase is probably statistically significant? Regardless of what the numbers are, I can tell that I’ve gained fitness over the last couple months, as I’ve had to recalibrate how difficult I think a workout will be. They’re becoming easier than I’m expecting to be (except over-unders which I continue to hate with the passion of a thousand fiery suns), and that is definitely progress that I can feel and believe in.
A different narrative I’m trying to own is that at 45 merely maintaining fitness is like improving, so actually improving is a meteoric trajectory
