Goudy: Sorry but I'm not too swift, and a little thick, when it comes to math or am I not understanding your post & numbers. The 410 dip & 320 chin, would that be weight added onto the body during the lift(s)? Or would that be including your bwt (220lbs) to form a combined weight overall. Example; dip 410= bwt 220 with 190lbs strapped on? If that 410 is a true added weight than you must use a lifting harness with a plate stacking rack for dips & chins. And you certainly are much stronger than the late, great Pat Casey and even Marvin Eder, both known for their dipping strength.
A couple of guy's I've known have done in the low 300's (weight added) range for dips in workouts. And some others in the 180- 200 lb range with chins for workout reps. In any case these guy's weighted in the 270-300 bwt range. Anyway, just wondering. Good Luck.
