Dave Meltzer documents Hamilton's ideas:
Hamilton proposes a scoring system based on breaking the scoring down to half-points, where a close round, a solid win, a dominant win and having the opponent on the verge of defeat could all be differentiated.
Under this system, if a fighter wins a round that's difficult to call, it gets scored 10-9.5. When it's clear that one fighter won the round, it's 10-9. When a fighter dominates the round but doesn't have his opponent in bad shape during the round, or if a fighter does major damage but the opponent gets a degree of offense in, that would be a 10-8.5. A 10-8 round or lower would be similar to how things are scored today.
Hamilton noted that in the Nov. 14 main event, where Couture beat Vera on straight 29-28 scores based on squeaking out Rounds 1 and 3 but solidly losing Round 2, his system would have likely judged Vera the winner. He saw it as 10-9.5 for the first and third for Couture, and a 10-8.5 for Vera, adding up to 29-28.5 for Vera, who scored a knockdown and inflicted the most damage in the fight in Round 2.
I've personally never been a fan of the ten point must system for MMA, but I think this is a very workable solution.
