I hate to disturb the polite exchange of frank and meaningful views by our regular combatents but:
I've never used Austote (never seemed to have the races I wanted to bet on) so I'm not familiar with how they operate. Is it along the same lines as the TAB, i.e. win pool divided by the number of winning bets and then a commission creamed from the winnings?
(And I hope my polite question doesn't earn quite so sharp a response as you got sportz).
