I just wouldn't try to tie them together that much since a good punch is really using different parts of the body from a lifting force. I also know they aren't really tied together from my karate instructor's instructor who was unlikely able to lift much more than 200lbs but could consistently measure a punch from 1500-2000 pps.

For psi of someone who could punch 600 pounds of force, I just divide by the size of their fist to get the pounds per inch? 

For my strength chart I'd take their best strength quality. For example, if they can deadlift 500 pounds but punch like a wimp they'd still be mid tier 1. 

If I go by 400s I could explain any minor discrepancies as the multiverse normal humans are just a tad bit stronger in general. Don't know why I didn't think of this simple solution. The only problem is trying to find how the average strength would tie into the average lifting force. I know it's not true for everyone but I'd like to know what would be balanced rater than making someone really strong and good at punching but the stats I give do not reflect this because I make his punching unintentional weak towards what he should be. Long story short, I need to know balance so I can make characters unbalanced in ways I desire as well.
