I'm not real keen to share to everyone how it works, for obvious reasons, anyway it looks like it needs some refining. I'm looking for a higher strike rate of winners. As you can see they are short odds. So to be on top we need at least 3 out of 4 to win.
Here's a few more.

Gosford 6/6 Jigsaw Julie

Ipswich 6/1 Hanson Crash

Lismore 8/2 Go Wild Bean
