Just to steal some high level points..........
we don’t really need to focus on the percentages of 85% of 1RM and above; second, the sticking point is not, usually, due to muscular imbalances, as we used to think and therefore address the matter, rather it is a lack of intermuscular coordination.
So, if you want to be really strong in your squat, bench and deadlift, stop going to failure as some gurus suggest or using percentages of 90% and above like some others do (if you are able to do 6×3@90%, you either have very low neuromuscular efficiency, or your strength and recovery are artificially enhanced), rather always use strict technique, lift explosively, and avoid the loads that make the sticking point appear.
It’s been proven by eastern European powerlifters (the strongest in the IPF federation, the largest and not so geared federation in the world) that mostly explosively lifting loads between 70 and 80% of 1RM (what’s called “Zone 3” in Soviet literature or “Zone 4” in Sheiko’s own scale) with perfect technique and no sticking point gives the highest transfer for 1RM loads improvement, especially in the medium and long term.
I think that to get good results with that system in powerlifting you really have to focus on technique and sticking point avoidance, which means sacrificing the loads, especially at the beginning. That is not something Americans are usually inclined to do.
In all seriousness, I get pretty happy when I find more and more anecdotal evidence that supports paths that I find myself going down. This just happens to be one of them, and I've had many in my training life.
By all means, if you think that maxing out and grinding reps and weight is required then do so. I just don't think it is anymore. It's not me being dogmatic, it's me pointing to evidence for guys who are frustrated and want to get better. I will continue to be "douchey" in that kind of way.
