Posing a question here as I haven't done any research for this angle.
Wondering if anyone has had any success with Betfair futures in racing and Sports.

Example: Browlow medal, the favourite is injured so won't be polling any more votes. He's drifted remarkably and there's a new favourite. Ergo, it's an easy green book.

Melbourne Cup, Cox Plate, US Womens' Open Tennis, Mens' Open Tennis, Formula One Drivers Championship, Doncaster Mile etc etc.
If a horse is scratched you lose nothing because you layed it early.
Seems more future favourites get rolled and green books are available, to favourites that go on to win in future markets.
That's the hypothesis anyway.

World Cup, Reality TV (Big Brother ugh) etc etc.
Green books everywhere in ratio to losses.

Anyone had experience or is it a mirage in reality?
