If Cher stays in....what will her odds be to win?

, she is 50 now. I think 1.2 is good value on her going out first during the final but a covering bet on her winning could be a good value. I think she could go down to 10 (if she does stay in, the market could be in shock and all over the place as the clear expectatioin is that she is going and rightfully so). So say: 400 at 1.2 to go out and 10 quid at 50 (going down to 10 if she makes it to the last 3) looks too easy some how, where is the catch?

could be that even in the last three, she could still be 20, who knows?
