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.
