Well we have a different definition of fighting then. If we meet on the street, you beat me up pretty hard in the first 5 mins, then u gas and for 15 mins we only more or less touch each other lightly, I would call you the winner of the fight. Also our faces and bodies would look accordingly.
What you are saying, basically, is that both fighters did almost no dmg in rounds 2-5 but fighter two is the victor due to barely winning those rounds, whereas my definition is that fighter 1 did 90% of the whole dmg in the fight and should win. Fighter 2 has 4 rounds to do as much dmg and if he can't he deserves to lose.
EDIT: That would actually happen given the current scoring system if judges learned to score 10-10 and 10-8 rounds better. When a round is a coinflip or really close, give out a 10-10 not a biased 10-9 and all is good.
