Stix, I don't know if you bet with Betfair, but their Place prices are quite generous.

My Oz Place system is currently showing a POT of 16% with NSW TAB but 25% with Betfair. If I can't bet on Betfair, then I record the Betfair divvy as the same as the TAB. So if I had been able bet every race on Betfair I would not be surprised if the POT with Betfair had been even higher. Over my latest 12 Place successes, 11 of my Betfair prices have exceeded the TAB divvy, and the other was more or less identical, even with Betfair's 5% takeout.

Some Oz Saturday races now have the SP facility on Place betting. I contacted Betfair to see if this will be extended to all races. They replied it would not be in the forseeable future, and could not give an answer if it will ever happen. Fortunately it is available on the U.K. races which is very convenient for me.
