0,5 point system would solve judging robberies
The Athletic commission takes the model from boxing where there are many rounds scored either 10 or 9, with 8 in case of a knockdown. This is flawed because MMA is more difficult to judge due to it's nature, and there are usually only 3-5 rounds. When a judge doesn't know who won, he should give 0.5 to each, but usually they follow intuition or some type of bias and give someone the round. If there is a clear winner 10-9 would be fine, and if there is complete domination 10-8 may be awarded.
Fights like Bisping vs. Hamill, Shogun vs. Machida, Machida vs. Rampage off the top of my head and many others may have different outcomes.
This may not however, be solution for fights like Melendez vs. Benson that could be scored as a draw, but that's why there are rematches.
Following: Cain , JDS, Werdum, Shogun, Machida, Weidman, Pettis, Aldo, Melendez
