DFS
 

Out of interest I was looking at today's DFS ratings using the following rules:

Races of 7 to 9 runners.
All runners must have had at least 3 starts.
Top three DFS selections.

Backing the top 3 to win, and also in boxed quinellas produced these results:

Win Results.
7 races for 7 winners.
Outlay of $21 for a return of $30.70 (Unitab divvies)

Quinella results.
7 races for 5 quinellas.
Outlay of $21 for a return of $38.20.

Would anyone have a data base/records of the DFS ratings to test the above criteria?

Thanks.
Michael.
