Merriguy, you are right - if a profit is made it will only be extremely small.

However, it appeals to me because there is a lot of action.

Yesterday was a bad day because of Domani's Girl - it paid $99 on S.P. Over the past two days the method is showing a loss is $12.18, or 32%, yet if I was laying them for an equal amount the loss would have been close to 50%. And the saving grace is that it is still showing an overall profit, and hopefully today will recoup yesterday's loss. If after many races the method is in profit I can increase the size of the bets. Conversely, if it is showing a bad loss I might back the selections on S.P. If we had access to a history of S.P. prices we could probably look at systems to see if they had a big win or loss, because the Back and Lay prices are exactly the same.

An observation - yesterday I looked at two races during their running. Our selection in one of them had the S.P. of $100 yet the last traded price on Place was $12.50. The selection in the second race had the S.P. of $110 yet the last traded price on Place was $18.50. Seeing that bookies give 1/4 of their Win price for the Place, it appears the Lay Betfair Place price on these outsiders could be good value. Unfortunately there is no S.P. available with Betfair.
