well, i mean any fixed percentage for vo2 is off-base too, at least it can be. if I did the following with any preconceived percentage rather than just ride as hard I could for each, I’d be in trouble, even with the last effort being lower power, I achieved the intended purpose by riding my max for that interval. Sticking to a percent, esp with erg, sets people up for a hard time, and for some maybe makes things easier than they should
