Here's a system I came up with during my form study.

Take the first 5 in the betting then apply the following.

1. Must be in the top 5 in average earnings.
2. Must have won at the distance at the course of the days meeting. E.G. If the meeting is at Rosehill -- it must have won at the distance +/- 100 metres.
3. Must be trained by one of the top 5 trainers.
4. Must be ridden by one of the top jockeys.
5. Must have finished 1st 0r 2nd in last 2 starts.
6. Must have raced in the last 28 days.

What do you think?
