Two closely matched fighters Charley Burley v Ray Robinson over one thousands bouts will have about I fight in 10 ending in a draw.
This is about right.They are so closely matched that often there is only 2 pts difference between the winner and loser at the end of the fight.
Now imagine that fight for real being scored by 3 judges who are not on Kings payroll (so to speak) Every round is going to be pretty close so its quite possible that in a 12 round fight 3 or more rounds would be scored as even. I think we can agree on that point. As most of the other rounds could possible be tough close rounds also. The judges would have a hard time deciding who in fact did win the round. Of course they cant keep scoring rounds even so they have to favour one fighter or the other. (There only human) and get things wrong at times

hence the Judges would have a difference of opinion as to who won the round and this would then be reflected on there score cards.
Problem is in the game is this. Lets call the judges robots there perfect, and every round they all can pick the correct score. So if nothing is done to stop this and its left at that, it means that all robots will score the same rounds a draw or pick the same fighter as each other to win the round. To avoid this, there has to be a percentage inbuilt in the program that throws up a chance that the computer judges do not all score the fight the correct way.
So that one robot gives the losing fighter the round, while maybe the other two go and pick the winner. That way you avoid all the perfect robots being correct for every round. and all scoring the rounds the same way.
Problem is its getting the % right. I think maybe its not working out correct and the bar has to be raised. But in truth only our programmer will know the reason.
