As for abstract maths, those are great no doubt. Too bad, in reality of game much more factors come in play. If you are using light weapon but have no healer with you, most likely you will die before you manage to do any significant damage to opponent of equal level. Or you will run out of stamina, which either lead you to dieing again or forcing you to flee. Simply because an opponent will deal more damage per hit and definitely not going to stay still another minute or two waiting until you poke him to death with your toy stick.
