         | It would be pretty difficult to do in a combat sport without

         | gloves, but some of the time the punches bounce off the
         | opponent's forearms, so you could get a false 'powerful' rating
         | from a blocked punch.
         | 
         | Worse, some of the best punches aren't the most powerful in a
         | kinetic sense, but just happen to very accurately land in the
         | right spot on an opponent's chin. Or they're well timed and the
         | opponent doesn't see it coming, so their surprise makes the
         | strike more damaging. Even if you could precisely measure punch
         | impact to the head from a distance, you'd be missing out on
         | some excellent punches that are less powerful but set up by
         | accuracy & timing. So yes it's basically impossible to measure
