That's why I'm saying in pattern of 5,4,3,2,1. For example 135x5, 155x3, 175x2, 185x1 then 140x4, 160x3, 190x1. No set done to failure, so for example if at 175 I feel I have 2, I'd just do a single then beat it on the second wave. I hope that I can get my single up without hitting my absolute 1RM (yeah I want strength but not too bad to do a risky rep). In about 2 weeks I'd test my 5RM again.
this conforms to your version of wave loading.

Well yeah only I'm trying to minimize fatique by doing 5 reps and lower. You would still say 72 hours?
