i think he meant the contact distribution of the knuckles you posted.
im assuming that you mean when you're drilling punches on a makiwara or something, because trying to be that precice when your in the middle of a fight isnt really a priority, or realistic. i mean i suppose if thats how you drill your punches, then in a fight your going to fall back on your structure and technique, but all of the variances in play are going to make it imperfect, by nature.
For whoso comes amongst many shall one day find that no one man is by so far the mightiest of all.
