MMA Fighters rematch a lot!

Our FightMatrix database shows the following rematch-related statistics:

• 2,307 bouts have taken place where the fighters have fought at least once previous.
• 196 bouts where fighters have fought at least twice previous…. and 24 bouts, at least three times previous.
• Two pairs of fighters have fought each other six times! (Travis Fulton & Rory Prazak, Brian Robinson & Nate Kopel)

In instances where fighters meet in their second encounter, the same winner has prevailed only 64.5% of the time.  If the first fight ended in a knockout or submission, this number increases to 67.7%.  These statistics prove that MMA is a very volatile sport compared to boxing, where the percentage of repeat winners after a knockout in the first bout since 1985 is almost 90% (I researched this myself).

Not many rematches have taken place after the first bout ended in disqualification.  In fact, its very rare, as we only have record of 19 said rematches.  The previous winner won 9 out of these 19.

How about when a fighter wins the first two matches by KO or TKO, and then rematches the loser for a third time?  In other words, does Quinton stand a chance on Saturday?  The dataset is extremely small, but the statistics show that the KO/TKO winner of the first two bouts, will win the third bout 89% of the time.
