I don't know anyone (except possibly raw powerlifters) who reports their max bench in terms of a paused bench press. Fact is, considering how hard some gym rats blast the barbell off their chests, I'm shocked more don't suffer from cracked sternums and punctured lungs!
I have to be honest, I'm still waiting for someone to crack their sternum. I can't stand watching someone bounce the bar of their chest... I just want to smack the shit out of every person I see doing this.
