You want all the KE to transfer to your target thus giveing a more effective and humane kill.
You need to take some more physics classes because a broadhead tipped arrow is not designed to transfer energy to the animal at all. It is disigned to pass through the amimal and cut as much tissue with as little resistance as possible on its way through. It does not kill by the transfer of energy it kills by hemmoraging. The more tissue cut then the more hemmoraging occurs. If the arrow stays in the animal then it blocks the flow of blood rom the wound to the ground and can make finding that animal more dificult.
Which is EXACTLY why I like a 3 blade mech. w/ a 2" cutting diameter. Or is my thinking just completely wrong here??
