I can’t say what works best for the TR system. But I know for myself, TR would never ever prescribe the VO2 workouts that I need to elicit adaptations. My VO2 interval power is such a high percentage of FTP that I don’t think the workout library has workouts to accommodate it. My most recent block had me doing 6x3 at between 140 and 125% of FTP.
So I do think that for some people that fall far enough out of the bell curve they just have to break out of the plan.
I mean it totally depends on what the workout’s power target is. But IMO, outside of just being a general guide, you shouldn’t be looking at power that closely during the VO2 intervals. Each interval should basically be a max effort. (maybe the first interval is 90-95% so you don’t blow up). But you will be doing less power over 4 minutes than you did over 2. But you’re still just comparing your personal power curve to a theoretical average power curve so it’s hard (impossible) to know what your workout outcome will be compared to what the AI model will tell you to do. But it’s probably safe to say if you’re overshooting the 2 min recommendations by that much then you’ll also overshoot the 4 min.
I guess idk what your absolute power is on these intervals but my VO2 intervals will vary up to like 10% between intervals and like 15% from the first minute to the last 2 minutes of a 3 minute interval.
