Something I am still kinda confused on is, how much does the level really matter? If you have your FTP set correctly, and you do a .95 IF workout but you level down and end up with a .94 IF workout, do you really think you are losing fitness? What if the workout AFTER that .94 ends up being a .96 with a lower level? DO you still feel you are losing out on fitness gains?
I definitely agree that the survey needs to be described better, and so should what the levels mean. I don’t really care what level it gives me. If I am struggling on a VO2 workout, but get another VO2 workout that is “easier” I still expect to struggle as long as the FTP setting is the same.
