For clarities sake,I have converted my earlier formula into English because it is very useful for those that are in it to win it.

Once you've decided how much the team will win by,do this.

Price = 0.955 to the power of the margin plus one.

And the only reason punters win,regardless of selection methods,is they are getting overs.
Not necessarily (how do you spell that?)on an event,but over time.
