Thanks jose,
Getting away from all the doom and gloom, as pointed out by CP I would like people to concentrate on the importance of getting the best odds, however miniscule.
Lets say I have 18 collects a week ( and that includes losing days to keep the sceptics quiet ).
I increase my collects by 1/10 of a point, and my bet is $400 that is $40 a collect X 18 = $720 a week X 52 = $37440 a year.
That's how important it is, which brings me to another point the tab rounds down to the lower 10c so lets give them the benefit of the doubt and say they are gaining .03c on every bet on every race of the year, the mind boggles of how much they are ripping off punters.

Again thanks,
All the best.
