I think this is the unique case where performing VO2max intervals as a % of your FTP from the ramp test is leading you astray. I think the TR ramps test algorithms work very well in most cases, but perhaps not when FTP is such a high % of PO @ VO2max.
It would be beneficial for you to program these intervals based on your PO @ VO2max from your assessment vs. a % of your FTP. I think you’ll have to bump the workout down so that the intervals hit the PO you desire. This should maximize the adaptive processes as you’ll be maintaining the desired stimulus for longer over the entire training session. I don’t think this is a good scenario for back pedalling.
I think @Bryce offers some good thoughts as well. Those shorter duration VO2max efforts are great without the accumulation of fatiguing byproducts associated with working well above threshold for long periods of time (i.e., accumulation of hydrogen ion, etc.)
I’m not sure if there is a feature that lets you do the above without changing the entire workout. @chad @Nate_Pearson?
