No I'm not talking about one rep max.
Just the number of sets people are doing once they have warmed up to their max weight.
Not interested in the amount of reps,just the amount of sets they complete at their max weight at a their chosen rep range.

e.g there's quite a few power lifting systems,that start at higher reps, lower % of max weight.Then week by week,you increase the weight,drop the reps,but some systems keep the # of completed sets the same with the max weight as the higher rep/lower weight but others decrease the sets.

I've just completed a rehab power cycle

% adjusted weekly

75 % x 6 sets x 8 reps
80% x 6 sets x 7 reps
85% x 6 sets x 6 reps
90% x 6 sets x 5 reps
95% x 6 sets x 4 reps

Then dropped back down to 75% but lifted the weight and added a rep.

I used to workout with another power lifter and he would pyramid up to his max weight for five reps and complete just ONE set.
When he{we} was able to achieve 5 reps at that weight he would increase the weight by 5kg{11lb} if not he would just try again next time that lift was scheduled.

So the question really is

Sets at max working weight
