It is impossible to lose one round out of five in a boxing match and lose the fight. One must score 10 points and the least points is seven.
The closest score in a 5 round fight with one winning 4 rounds is:
10-9, 10-9, 10-9, 10-9, 7-10 or 47-46.
So if you win 4 out of 5 rounds in a boxing match, and no KO, you WILL win the fight.
Second, there should always be a tie breaking category used for such.
The one thing missing in this study is quality of sound. Are these equal? How about video quality? Photo quality?
