Yes as suspected the loss looks as though it would be about the same as backing all 3 @ level stakes.

But really that's my point, lets say we have SR of 30% and a POT of 10%, so instead of backing @ levels we make each bet the first leg of a running double,

without actually doing the exercise I'd guess the POT would remain at 10%?

Chrome, in my example I just guessed that the average price for the winning fav is about 2-1, would that be right?
