Just did a quick check on yesterdays results using this system
outly $35
profit $16
ROI 46%
longest run of outs was 5
because of the dau night meetings i went race to race link this
ROCKHAMPTON (QR)
MUSWELLBROOK (NR)
COLAC (VR)

untill they were finished then went
CANTERBURY (SR)
MOONEE VALLEY (MR)

you are always going to get variations in this system depending on how people test and at what prices they test with....but as a spot type of play it is very interesting....but would be time consuming watching all the races all day
