Lords of Magic had an automatic battle calculator. It was not an automatic win, however, because it calculated losses on both sides and so you could end up with some dead party units. I think it was intended to be used mostly for trivial battles in order to save time, but you could use it in any combat situation.
I can jump maybe a couple feet high from a standstill. I don't see how this should give me an advantage in combat. I guess kick-boxers do jump a little bit, but not really that much. Pole vaulting with a spear or staff might be cool once in a while.
