Hi there,
I notice AI FTP prediction changing day to day, especially before completing the next scheduled workout. i.e. Day 1 gives me one value after I complete the workout & give feedback. Day 2 comes around and before I even start the workout, the AI FTP prediction goes down, as though something happened overnight that pushed it down.
Is that supposed to be this way without any possible cause for the prediction to change (its always a decline for me) and is rather discouraging.
Are they structured workouts or zwift races or group rides. I think the evaluation of now TR workouts might occur at a different time.
Structured workouts per training plan through TR.
MMM ok, it feels like im doing what ive been prescribed and then the goalposts or goal line keeps moving in a negative way. Each time the predicted AI FTP starts out showing a big jump and as each day passes, not necessarily thru workout, but more like what I described, in between workouts, the FTP prediction decreases. Could really be like you suggested - a timing mismatch of the projection being run during that window between my workouts.
Post your past 4 weeks and upcoming if you want more than guesses.
I recommend going into your calendar and editing your planned workouts that are coming up to set the workout start time, click the pencil button to edit and set start time is just below the date. This in very hypothetical (hopeful) sense… should then let TR know when you are going to do it and how many hours between training.
I recently did that on my workouts and the AI sparkles adjusted quite a few of the workouts and also inserted a yellow day as a result. So if you know you are consistent with a certain day/time on some days… might be worth it to adjust those on upcoming workouts. Unfortunately there isn’t a batch way to do this to your entire training plan (see forum topic on it) Set default workout start time - #3 by Helvellyn
I have been slightly perplexed by the same pattern.
My most recent example
Saturday - Threshold workout completed as planned, Rated it Hard, Hard prediction was 80%.
AI FTP Prediction recalculated after ride 253 W.
Sunday - Yellow day , just checked app to see what workout was scheduled for Tuesday.
AI FTP Prediction recalculates to 252 W.
Monday - rest day as planned by TR. I check app again out of curiosity.
AI FTP Prediction recalculates to 251 W.
48hrs of following the plan with no new data as expected and the AI FTP Prediction changes on both days……. I must be missing something but this makes no sense to me.
curious, how many times in the last few months have you ridden your bike when it wasn’t on your training plan?
Also… of those unplanned days, how often was it on Sunday, Monday or Tuesday?
If AI is fully AI… if you occasionally do unplanned rides, I would imagine that AI might have predicted you to have went for a ride, unplanned, which would have helped your overall fitness??? But then again… it likely isn’t that creative…
Thanks for reply - just looked at my original post , for some unknown reason I put the rest days as Monday and Tuesday, probably irrelevant to my “issue” but I’ve edited and corrected my post.
In reply to your thoughts ntisdell, this is my typical pattern of workouts on the plan over the last few months. One workout typically Saturday , and 2 in the week. Usually Monday and Wednesday.
Sometimes I shift the weekday workouts by a day due to my work… as this time …. Is that enough to see this AI behaviour?
Hey y’all! 
I just wanted to follow up on this one and a few other threads to let you know that the team just tracked down and fixed a bug that was causing AI FTP Prediction volatility. In some cases, an upcoming workout in your plan could swap to the next best workout (instead of the first best). If your workouts and AI FTP shifted without anything changing on your calendar, you were affected by this bug. The fix has already taken effect so you don’t need to do anything on your end for your workouts to be set correctly. 
As always, stay in touch and let me know if you run into issues moving forward, but we think this is going to play a major role in eliminating FTP Prediction volatility moving forward.
