Simple greyhound system
 

Rule 1) At any venue mark any dog in box 1 ONLY that is a last start winner(it can have won it's last 2 but NOT it's last3 starts
Rule2) No bet if it has NBT(no best time) or FSH(first start here)next to it's name.
It can throw up some shorties but it generally goes OK,just sorry I haven't kept any records.
