It is not 100% the same, but the autoregulative principles are there.
Jim basically uses same idea as RPE for the athletes he’s coaching, since he does not use%, but observes bar speed and other factors for determining the TM. Again, this does not change from session to session, but I personally think it does not really matter.
I liked how someone called the RPE as common sense. It is just another way (a good way, I admit) to deal with autoregulation in training. I mean that I’ve seen RPE based programs before tje term was not even used.
I think that closest equivalent for RPE would be the Beyond training.
