If you pulled all these guys out of the super suits the honest truth is that most(99.9%) of these guys would only be as strong or even weaker than the raw or 1-ply guys of 30 years ago. If you look at the deadlift which is the only real rawish lift left across powerlifting, the best lifts have only moved up 75-100 pounds in the last 25-30 years and that's with deadlift suits that add on average 50 pounds to the lift. If you left the suits out of Powerlifting, it would be a lot closer to Olympic Lifting, where after you've played with all the drugs and form tweaks, you're still only be adding a few kilos to a total with each generation.
I bet that's got to hurt some of these guys, to know that despite all the layers, all the plys, canvas, denim, lions, tigers and (muscle) bears... oh, my.... they're really no stronger than some old 1970's cat that threw on his old marathon and walked his squats out.
