Thanks for the link.
The punch that he gave was 60 mph. That is a good punch. But as far as I know not exceptional. It seems that a speed like that is not uncommon in boxing or TKD, muay thai, etc.?
Force = mass
Power = force x velocity
If you have 20lbs of mass behind a 100 mph strike, you have less power than if you can recruit 34lbs of mass behind a 60 mph punch. (just throwing numbers out to point out that the raw speed of a strike is not the ultimate litmus for how much power (or potential power) there is there)
