Rule 1: Operate on races with 10 to 17 runners (inclusive).
Rule 2: Consider the horse who is on the fourth line in the pre-post betting. If more than one, pass the race.
Rule 3: The horse must have won at least one of its last three races.
Rule 4: Eliminate maiden races, jumps races, races limited to apprentice jockeys or female jockeys, and races where the pre-post favourite is less than 5/2.
Rule 5: If more than one race is left, select the race where the odds of the first three lines in the pre-post market when added together is the highest number.
Rule 6: If still more than one race, choose the race with the least total prizemoney.
Rule 7: Do not bet if the track conditions changes during the day.

I like the drift of this system Glen. With the rule about ignoring races where the favorite is 5/2 [$3.50] or less, it implies a certain confusion among the betting public. This uncertainty seems to be what is being exploited with this system.

I'm a bit confused about some of the rules. Rule 5 'if more than one race left" From what? Does this system end up with one bet from all the races?

Yes, the rule does mean it will end up with one bet from all the races.
