Got a new system and here are the rules:
1. Consider only upcoming blacktype races
1a. NO 2yo or 3yo races!
2. Consider only horse's last five starts
3. Consider only wins in those last five starts
4. Assign points only to metro wins (for each win) as outlined in the table below:
G1 - 16
G2 - 8
G3 - 4
LR - 2
Open - 1
Of course, it comes up with the favourite lots of times, but dutch betting the top two or three can sometimes throw out a surprise result in a Listed Race where a horse won a G3 or G2 four or five starts ago. (I think it was Topsy who who uses something similar).
This is a fun system, with limited bets, and a quick rating system which is great fun if you don't have time to do the form for a lot of races and would like some bets on the weekend.
Interestingly, it actually shows a profit, if used right
Depending on prices, I like to back the top two or three and also take Quinellas with the other rated horses
