Lets have the players decide the force of their punches themselves. The punch force they have now is absurd, but to determine one's true punching force, too many factors need to be taken into account. For example, Gregor and Ido have even strength, but Gregor should be able to punch harder thanks to the additional weight and size of his body. However, Ido has metal bones and tough muscle, which decreases the amount of energy expended on deformation of the arm upon impact, transfering more energy to the opponent's body. Gregor still should pack more power, but Ido's punch will strike as if he had brass kunckles on, so it actualy becomes harder to determine which would have the upper hand, even though their physical strength is even.
