I checked a Bet Method yesterday. There are three layers of betting, the first layer is $15, the second is $10 and the third is $5. I'll show the three layers per race and I'm betting on on Betfair S.P.

Yesterday it would have struck a 10% profit on Unitab. I only looked at Betfair for one race. The winner (Hawkesbury R2) paid $24 on Unitab but $40 on Betfair S.P., so I think I can safely assume the Betfair profit would have been quite high. Today we''ll see...
