The worst overrounds appear in ante-post markets, where the uncertainty justifies \u2014 in the bookmaker\u2019s view \u2014 margins that can reach extraordinary levels. The individual difference may be small \u2014 perhaps 5\/1 versus 11\/2 \u2014 but across hundreds of bets over a year, that cumulative margin is the difference between a profitable punter and a losing one. With the assistance of Equinedge I hit several races yesterday and netted over $1100 in profit. The take varies from state to state and the money is used to pay taxes, purse money for the horsemen, expenses at the track, and the track’s profit. Those who bet casually subsidise the returns of those who bet carefully.<\/p>\n
