At the end of a match, BOTH girls need to agree on a winner and loser. If there's a dispute that can't be worked out BOTH girls get a forfeit and are out of the competition. That may seem kind of harsh, but it's the only way to insure girls are talking and matches are fair to both wrestlers.
Isn't there the potential for this to cause more problems than it solves. Say for example Fighter 1 and Fighter 2 fight, Fighter 1 appears the rightful winner but Fighter 2 disputes this, now if Fighter 2 sticks to their guns (even if Fighter 1 won legit) then Fighter 1 ends up being out. Essentially the losers can hold the winners to ransom giving them an unfair advantage because it means the better fighter has to re-do moves to give the other person an advantage to have a hope of being allowed to claim victory.
Imagine if World War 2 played out like that.
Allies: I win!
Axis: Erm no... the Russian winter was unfair you need to re-do that.
Allies: Well I think it is realistic.
Axis: Fine then we both lose.
Allies: But... fine, ok YT.
Axis: I deploy super ninjas and kill you instantly! YT.
Is there any way someone or someones neutral could be found to settle disputes? I know then people could complain about favourtism but at least for someone to get screwed over that way someone has to claim something was unfair and then other people need to agree it was unfair, the risk is still there but surely it is reduced?
