I've been playing around looking at tipster selections recently although have no systems based on them yet. I have a promising system selection method that might be worthwhile though. Here are the rules for those interested following it. Its a bit of work and you need to be quick with maths though.

1. Find all meetings with 3 or more tipsters at 2ky/sky (takes about 1 min)
2. For each race find those races which have only 5 selections across the 3+ tipsters.
3. Wait till race time and if you can make at least 15% dutching the selections then apply a dutch bet using the 5 selections.

Nothing more then that.

Here were the results today :

Grafton Race 5: Profit $29.40 dutching to $100 before commission.
Sunshine Coast Race 3 : Profit $17.32 dutching to $100 before commission.
