I have used Bernie's method below DS=1, NR=1, DLS <=21
I have left out maidens, races where horses have never had a start and races with less than 8 runners

picks for Saturday 25/8 are

Belmont Rc3
Belmont Rc4
Doomben Rc4
Gold Coast Rc5
Newcastle Rc6
Newcastle Rc8

Let's see how they go for interest sake.
