I have a classic gun hunting book: "Shots at Whitetails." His coment on bullets is that he wants a bullet that uses its energy to damage the deer s.t. a perfect strike is one where the bullet falls out of the hide when the deer is skinned.

Applying this same theory to archery, I'd want enough blades with enough cutting radius such that all the energy of the arrow goes into cutting the deer and none embedding itself into the ground on the other side of the deer.

Unfortunately, since one hit changes so much compared to the next, I'd have to know ahead of time which hit I was going to get so I'd have the right broadhead for a particular hit.
