Hopefully someone out there can help me.
I need a staking plan for backing four horses per race, the obvious one is Dutching, but occasionally I have a losing run of four races and trying to recoup losses on the 4th or 5th bet becomes expensive.
My selection process is pretty good (I think) with 205 selected races for 135 wins= 65.85% strike rate.
Any help with this will be greatly appreciated. Cheers.

For anyone interested heres todays selections:
Caulf. R2 1,2,8,5
Caulf. R3 1,6,3,5
W/Farm R5 1,5,4,2
W/Farm R6 1,5,6,2
