The h bp hasn’t been contested so hard to say there. I actually train from blocks though for the pullover and press/push so I have a good idea. I can do just a little more than what I bench, 10-15 lbs. I have some shoulder issues as well, so I know where you’re coming from
For the squat, I would say at the time of the contest I was somewhere near 525 parallel give or take and got 800. That was pretty much max effort.
For the deadlift, I really think a lot more variables come into play. I think I had more in me, but I would say somewhere in the neighborhood of 100 to 150 lbs over your floor DL.
Just to ball park. Anyone else?
