Workout completion, AIFTP bump and Progression level adjustment


I’m not sure if this is a bug, or expected behaviour, but I thought I’d raise here first to see what others think and if it’s just me looking at it wrong:

The issues relates to my threshold PL adjustments with AIFTP thrown into the mix. Here’s the order of relevant events/observations:

  • 10th Apr: Completed Mount Regan a 3.8 threshold workout. FTP 270. Workout summary screen reports a threshold PL adj. 2.8 → 3.8 (+1.0)
  • 17th Apr: Completed Sheep Mountain, a 4.0 threshold workout. FTP 270. Workout summary screen reports a threshold PL adj. 3.8 → 4.0 (+0.2)
  • 17th Apr: An AIFTP calculation is offered post workout, which I accept. It tells me my new FTP is 279 (woohoo), and adjust my levels down, specifically threshold PL is now 2.3 (if I remember correctly from the AIFTP screen that explains the down adjustments).
  • 17th Apr, some time after above step, I look at my PL on the Career page and my threshold PL is 4.0. When I hover over it is says Threshold 2.3 → 4.0 (+1.7).

On the surface it appears though my PL has been calculated by adding the tonight’s workout to the PL calculated by AIFTP, which doesn’t seem correct since the workout was done at the lower FTP prior to AIFTP calculation? Surely my threshold PL should be 2.3 or 2.5 depending on the order the PL adjustments are applied.

Just to labour my point in case I’ve not explained it too well, given the above order of events the process appears to be:

10th Apr: 2.8 to 3.8 (+1.0) for Mount Regan
17th Apr: 3.8 to 2.3 (-1.5) for AIFTP
17th Apr: 2.3 to 4.0 to for Sheep Mountain

Should it be:

10th Apr: 2.8 to 3.8 (+1.0) for Mount Regan
17th Apr: 3.8 to 4.0 (+0.2) for Sheep Mountain
17th Apr: 4.0 to 2.5 (-1.5) for AIFTP

Here’s some pics of the above also:


Apologies if I dragged that out longer than necessary, I just wanted to be as clear as I could.

From what you posted, this sounds like a bug. My guess is that AIFTP wanted to bump your FTP prior to you doing Sheep Mountain, so it internally decreased your PL, and then you did a 4.0 workout so it bumped your PL.

Definitely something to report to TR support so they can dig into the apparent timing issues and fix this corner case.

Thanks for casting your eyes over it.

It didn’t make sense to me either, but you never know… I’ve been wrong about things that don’t make sense before! :face_with_open_eyes_and_hand_over_mouth:

I’ll create a support ticket.

TR released an update around AIFTP and there seem to be bugs (though some forum members were insisting on saying this was how it should work). Check out Updates on how AI FTP Detection is triggered!

Good shout. I hadn’t got around to raising an issue, but will stick an abridged version there instead for now. :+1:

Hey there!

Looks like your Progression Levels were taking a bit longer than usual to sync up. I refreshed your account and things are looking as they are supposed to now!

Feel free to let me or TR Support know if you need a hand with anything else!

I did notice earlier today that it had come back to 2.3 but hadn’t got around to mentioning.

Saturday’s threshold workout was showing as a 4.1 earlier, but I see it’s a much more reasonable 2.6 now. I was prepared to brave the 4.1, but now its come back in line I’m feeling somewhat relieved! :slight_smile: .

Thanks for the intervention!
