Not sure how you can go max bet unless you think the fight won't be competitive or go to a decision.
In my opinion, in the last five Light Weight title fights that went to decision judges went 1-4 with correct decision.

Copied and pasted from Frankie Edgar's wiki with an added column "Who Really Won"

Win 12–1 B.J. Penn Decision (unanimous) UFC 112 B.J. Penn

And just to show that I am not alone in this opinion. Here is how Sherdog scored these bouts:

I used the Sherdog play by play because they are the only reputable site that has three people score it.

You may think that these fights are only controversial because of Edgar's style but I think there is more to it. This is the most competitive weight class in the UFC and the title fights reflect that. MMA judges make mistakes all the time when fights are not competitive, so we have to except the strong possibility that they won't judge these extremely competitive bouts with any degree of accuracy.
