Hi Mark,
A friend of mine suggests changing the 2x to 1x as he got far better lay strike
rate.
131/137 lays
95.62% lay strike rate ( average pay out 1 in 22.83 lays )
current lay win sequence 50.
this was tested in Bet Selector with no odds cap, from 1/1/11 through 1/5/11

Will be interesting checking with your odds cap of $10 using the Betfair lay odds?.
Today's bets using the 1x are
1.27pm PAK R3-6
1.48pm QIR R2-2

Will the current win sequence of 50 be finally be stopped today?.
