10 point must system where aggression and offense is awarded while defense is ignored. It is also highly subjective....the guy who gets the most take downs wins....
There is a number of things they score on takedowns ratio of strikes kicks and punches landed....They go by submission attampets and doing counters if you need more info go to mmafighter.com they have listings
If the fight doesn't end via (T)KO or submission, the fighter who keeps walking forward genrally wins because the judges are usally morons.
In all seriousness, it is judged on effective striking graplling, agression, and octogon controll.
The winner of the round gets 10 points, and the other fighyet gets anywere from 1-9 points, althought it has to be VERY in even to get less than 9.
Fights are judged round by round. The winner of each round is given ten points, and the loser is given nine or less. So unless a fighter got a point deducted or lost a round very badly, most rounds will be scored 10-9. If a fighter wins all three rounds, the final score will be 30-27. If the winner of the fight wins two rounds and his opponent wins one round, the score would be 29-28. Five-round fights are scored the same way, there are just more rounds to factor in, so a five-round fight that goes the distance might be scored 50-45, if one fighter won all five rounds.
