Thanks, Demodocus.

My problem is determining the price which I can't do because I lay them via S.P. But from what I've read here the method's not completely hopeless and has some promise.

Assuming 2 prev starts as a min and not using any Rating's filters.
Last Start winners Not on Home track and min SP >= $6, you could scrape 1% POT for the Lay. i.e. Last 809 days $1k liability, 5.5% commission, 956 bets, 891 Lay wins, $9,538 profit.

Second Last start winners were too hard to grind out a Lay profit unless you get down to a handful of bets.

Stick with Laying Longshots MG, like you used to.....lol

Thanks, RP.

I've had a look at today's results. I can't be too precise about S.P but there were 18 selections (Ascot R7 has yet to be run). So far there have been 3 accidents of $2.30, $4.20 and $1.90 (Unitab divvies) - I would safely assume that laying the method today on the Exchange one would well be in profit.

Unfortunately No 1 R7 won - it's Unitab divvy was only $2.30 so I'm fairly confident the method laying on the Exchange would have shown a profit.
