Workout level of the new workout should be higher
This is incorrect 
More is not always best. The system will recommend higher or lower workouts levels depending on your training data to keep your fitness gains on track.
@Cooke based on the screenshots youāve shared so far, it looks like youāre doing some of your TR workouts outside.
We have a known bug that Iāve shared in a number of other threads that gives inflated FTP predictions when athletes are doing their workouts outside.
That drops slowly over time up until the actual day of FTP Detection. The final detection is actually accurate; itās just the prediction that is slightly inflated.
This would explain why your prediction is dropping over time, but youāre still seeing solid gains each month.
For the time being, try to focus less on the predictions. Weāll get this bug sorted out ASAP.

This comes from the linked thread:
The āSetsā terminology is only for when intervals are closely packed together with longer rests on either side. A āsetā of 30/30ās would be a set in an on/off Vo2 workout, whereas a 4x12m threshold workout would contain 4, 12 minute intervals. HOWEVER, a single 12 minute interval in this instance would also be considered a set.
Itās confusing but only because there has to be a way to make clear that one 30 second interval isnāt the same thing as one 12 minute interval.
I think we all intuitively know what they mean but then we start over thinking it a bit and it gets muddy.

Totally agree with all of that.
IMOā¦
VO2 - 30sec/30sec/30sec/30sec/30sec/30sec/30sec/30sec/30sec/30sec is a set
SWEET SPOT - 1x15min is a set
OVER UNDER - 3min/2min/3min/2min/3min/2min is a set
the language is a little hazy but I feel like common sense makes it pretty clear. A set is a ābatch of workā which may or may not include small interstitial breaks within it. Sets are separated by more substantial breaks.

Thanks for helping to clarify!! 
But the first phase of my plan was almost completely done indoors? So that doesnāt explain whatās happening at all.
It might explain whatās happening now, though..
Were your workouts scheduled to be indoors during the first block?
Also, was your experience then the same (high predictions that dropped down to your detection, which was an increase in fitness)?
All of my rides have completed in the way they were scheduled indoors or outdoors and I have been having the same experience with predictions throughout all phases, high predictions in the beginning and then gradually dropping all the way through. Now my predictions are in the negative and I feel the training plans are holding me back, I have replaced workouts with harder variations and the prediction thought they were too difficult for me and then I complete them and it thinks I havenāt succeeded or failed the ride or something because my prediction drops further. Itās like itās holding me back and then punishing me for actually proving it wrong.
where is the check volume feature?
click on your training plan in the calendar to open the side drawer. itās at the bottom next to Edit Plan
Hey yāall! 
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 donāt 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.

Can you say more about this? How is it the 2nd best workout out of thousands to choose from is causing AIFTP to jump multiple numbers? Maybe Iām just misunderstanding the point?
Edit: I just read your reply here. This one makes a lot more sense, so maybe Iām confusing the two issues? Breaking up with TrainerRoad? - #23
Those are two separate issues.
The first is a bug that we discovered and fixed regarding FTP Prediction changes that happened on their own without any input to prompt them.
The one you linked that āmakes a lot more senseā is another FTP Prediction volatility issue, but itās driven by Outside Workouts.
That first issue allows for a sort of ping-ponging between workouts, which makes the FTP Prediction unstable.
I donāt have a ton of other details about this issue, but if you have specific questions, I can see if I can get some answers.
It might be the case where when a workout just slightly exceeds the failure rate limit ~2.5%, it gets automatically counted as a failure, even though it will very likely productive.
