I can see that it would properly work better with distance horses because they run to get fit and can be misjudged were as over the shorter distances could be good lays for a varity of reasons. I agree with the tab numbers as the handicapper can class better than I can and I have always used tab number to separate horses rather than price –this is more of an average thing so long as you use it with reason.( Sydney and Melbourne have so many tracks that all play differently whereas Brisbane, Adelaide and Perth have only a couple of tracks making the racing much more consistent, even if the class of racing is not as strong.)The track part I am not sure and what you say makes sence. So for me that system comes down to one factor the best price markets are Syd and Melb looking at the bookies % and not that it wont work long term but for me the fact that it doesn’t work in these two states only adds to the percentage you have to beat long term. If it was the other way around great but you can only work with the figures you have and its best to know rather than continue on blindly with out any chance and so the facts are don’t bet in Syd or Melb or under 1600 meters and stay with the better class horses.
