Indeed, an excellent question. I've consistently broken more boards with a hammerfist than with a palm heel, shuto or reverse punch. But your point is well-taken, and would apply to any technique. Each individual is different, and the hammerfist works best for a short, 50-year old mesomorph like myself.
