Then you would not be looking at the information available from the majority of successful MMA fighters.
As far as I know, only 1 person in the UFC uses anything that appears similar to karate to any great effect 1 person in the history of the UFC. Correct me if I am wrong.

Wrong. Chuck Liddell's techniques come from a katacentric system similar to many okinawan karate styles. Its just that after Hack learned the system and how to fight with it he eliminated the kata and called it Hawaiian Kempo. I have seen the similarities first hand since I used to train with a Hawaiian 8th Dan trained by William Chow. I used to help him prepare his one student for his BB.
