1annandale1, good point, but not everyone would act upon it.

A few years ago one of my friends backed a football team (Benfica) at $50 to win the Champions League or one of the European comps. Benfica made it to the finals, and I told my friend that if he backed the other team for a certain amount he would obtain a good profit whatever the result of the game. His reply was "no, with me its all or nothing".

I suppose its up to the individual.

As a matter of interest, due to a late scratching Townsville R2 only had 10 runners (the minimum for the system is 11), but having already placed the bet I was unable to cancel it.
