I won $3.64 today.

However I have been under the impression that instead of laying the selections it might be better to back all the other other horses in the race.

I haven't recorded the results during the testing period but have done the comparisons for yesterday and today.

Yesterday the lay system had a profit of $72.54. Backing the other horses in those races on Betfair S.P. with $5.00 bets had a profit of $146.40.

As mentioned above, today's profit for the lay system was $3.64 but backing the other horses would have produced a profit of $79.15. I backed them on both days with the NSW TAB and surprisingly am in profit. And boxing them in quinellas has also been profitable. The quinella for Geelong R7 paid $130 ($150 on Unitab).

Betting S.P. is more profitable then laying, yet surprisingly the liability on betting is much less then laying. Both days indicates that the profit on betting is higher and that the liability is less.

The only drawback is the strike rate. Today I lost on only two races with the lay system but 14 with the bet system because the fave or second-fave won.

Tomorrow I'll start a new thread listing the selections that I will bet.
