Hi Blocka,
My data base can do margins.
I found the 4th last start without the margin rule to be more profitable in this particular exercise.

The place percentage refers to 1st,2nd,3rds.
The 5-49% was where the value was , admittedly I shoehorned the stats that were in front of me to create a profit at that point in time .

It probable shows a profit because it is a professional winner & not a professional place getter
Maybe this 49% rule should be scrapped. But that is where the value was.
Those results could change the following year , that`s the frustrating bit of system analysis.

The figures showed that higher the place SR the lower the dividend.
.

Crash has some valid points about system testing ,which I agree with.
Especially the 70% & 30% of the data base.
The margins makes for a logical argument but getting the value is another.
The plan pulled a number of double digit prices so it has some merit.
Why it works best at provincial rather than Country & Metro ,is a mystery to me , but thats how the stats fell.

The original stats I have shown had the margin left out because it did not show a profit, that was the only change to the original result of that +663 result which equated to approx 25% POT
