So the Diego - Pearson decision has me wondering if the current 10-Point Must System is the best way to score a fight. The UFC's own rules about scoring have always seemed vague and weird to me (UFC judging rules can be found here ) For example in sub-section B the rules state, "The 10-Point Must System will be the standard system of scoring a bout. Under the 10-Point Must Scoring System, 10 points must be awarded to the winner of the round and 9 points or less must be awarded to the loser, except for a rare even round, which is scored (10-10)." However, this is seemly contradicted in sub-section J in which it 10-10, 10-9, 10-8, and 10-7 rounds are discussed. Basically if you start with confusing rules you're going to get bad decisions more often than you should in my opinion.
