I’m looking for something different: not which load will theoretically increase my FTP more, but did I handle the load I did well.
Let’s take your example, and say that TR predicts my FTP would go up more if I did the HV plan instead of the MV plan. I do the HV plan, but I cannot handle the load, and AT has to keep dropping the intensity / I keep failing workouts. What I’m asking for would provide a look back that says: we predicted you would be at XXXX, but given what you can handle, you are only at CCCC. So going forward, when I’m looking at how much load I can handle, I have an evidenced based guide.
Does this distinction make sense?
