Thanks for your suggestions.

However at the moment I'll keep it simple even though I'll keep in mind the suggestions. The only filter I'll currently apply is that the maximum number of runners per qualifying race is 11.

Today's races and selections are:

Townsville
2/1, 3
3/1, 3
4/4, 5, 9
5/6, 9

Seymour
4/3, 6, 7
5/1, 5
7/9, 10, 11
8/1, 3

Taree
1/1, 8
4/1, 4
7/4

I'll be betting them to Win and box quinellas.

Win outlay is $24.
Quinella outlay is $15.
