It has worked pretty well in the amatuers and I cant see how it would do anything but help in the pros. Its not hard to score a pro fight and if there was a bad call with 5 judges it would be easier to weed out the bad judges. Also, there should be much tougher qualification for someone to become a judge and medical requirements should be stricter.
ARGGGHHH!!! What a massive cluster-**** you'd end up having. Let's also have two referees at the same time to micro-manage the action...
Judging in the amatuers is objective. Whoever lands the most punches wins the round. It dose not matter who lands the hardest ones. Knockdowns count as much as pitty-pat punches. Judging in proffsonal boxing is subjective. The judge decides who they think did better that round. Everything is just a guideline. It would not matter how many judges are used.
