With a higher FOC the arrow is going to be able to take the straighest path through the animal more easily than a lower FOC which would deflect much easier, losing energy along the way.

The KE won't be any different but the loss of KE as it goes through the animal would drop off much faster.

That's just a thought that popped in my head, I don't know if it would actualy be true.
