Thorns, I've been looking at a similar Lay system with TAB no.1 but haven't kept any records because there isn't too much action. The rules are

1) TAB no.1
2) Won last start.
3) At least 1 kilo heavier than the next horse.

There were two selections today.

Warwick Farm 6/1 - beaten. (Started $3.40 TAB)
Belmont 2/1 - beaten. (Started $2.80 TAB)

There were no selections yesterday or Monday.


Party, I'm under the impression that if all faves were backed "at the jump" on Betfair then the loss would generally be about 5%, so too with laying them because of Betfair's commission.
