Merriguy, I looked at BAT for today's racing at both venues - it would be expected that this be somehat more accurate than Unitab prices because it shows the final Bet price on Betfair.

There were 26 selections for 24 smiles in the $6.00 to $9.90 range as shown on the BAT site. Below are the results.

The total liability on the two accidents was 11.40 units.

24 smiles X 0.95 (Betfair's takeout) = 22.80 units profit.

By my reckoning that is a total profit of 11.40 units, or exactly a 50% profit. However the actual profit would be slightly less because I've used the Buy price and not the Lay price. Nevertheless, still a very good profit.
