In respect to Duritz, thought I'd better reply here as we getting away from his original post.

No, sorry if I confused you , those results were the result of applying your ideas to MY system, BUt it's hardly rocket science, so the incredible difference when applying the distance rule is VERY INTERESTING to say the least.

I only applied Pre-Post prices as quoted in Tab-Form (don't have the capacity for SP etc)

I had already discovered that races of 2000 or above were less profitable so YES I included 1400m - 1950m.

Haven't applied the SP with the distance rule yet but will have a go.

Thanks for the info, Party.

Well we have helped each other here as I will now lower my distances and see if there is an improvement.

The above 1400m. rule has very sound logic to it when you think about it. There is just too many hairs being split below that distance and it must work against most systems and Handicapping efforts. Too much becomes chance [possibility would be the correct term] in the shorter sprints.

Let me know how you go with the SP. Perhaps because the shorter prices attract more money, the slightly longer price anomaly I have shown with my bets is due to overall better 'value' ?
