I hate to shill other sites but I really love this site because you don't pay for anything unless you want to pay a tout for some reason (DO SO AT YOUR OWN RISK) but the betting tools are really incredible and completely free which I love. I ran across this site about a month ago and really loved it. You can track your picks and plays there, but the MMA stats are really awesome. You get a quick breakdown of UFC debutante statistics (win/loss), fighters who missed weight stats, late replacements, fighter age analysis, and my favorite, the Over/Under betting. You just set your filters and let it go. You can see how many 115 pound chick fights finish in TKO, SUB, and decision and exactly how many finished in each round and by what method. I personally used it to come up with this break-even rate for my Excel file.
This chart essentially says the fair line given the fights that have happened in the past in the specific weight division. The average price is what the price would be given the percentage of fights that start round 3 or go to decision. I use it to judge fights by thinking, if so and so aren't good finishers and are durable, why is the decision prop priced at -200 when the average price should be -213 for 115 pound women.
