Gregstrom, the formulae are equivalent.

B + [A/40 * (40-B)] =
B + A(40-B)/40 =
B + A*40/40 - A*B/40 =
A + A - A*B/40

Remember that Head Prot is actually totally discrete from Body Prot, unlike Natural/Armor Protection. That is, a creature with a Body Prot of 25 and a Head Prot of 5 (like many sacreds without helmets) will take approximately zero damage from humans wielding daggers most of the time because they hit the body, but sometimes they hit the head and do about 7 points of damage. So expect a high variance in damage taken if you have low head prot.

I'm not sure exactly how it's calculated whether something hits the head or the body. I seem to have observed that the relative sizes of the creatures involved makes a difference, as does the length of the weapons, but I'm not sure and I haven't ever checked the debug log to make sure.
