This is very similar to a system I came across a few years ago called the Dejavu system (for obvious reasons). The theory is that horses are creatures of habit and tries to target runners that are running at the same scenario of past successes. It goes like this:

1. The horse must have WON ITS LAST START AT THIS TRACK, DURING THIS CAMPAIGN. This win is called the QUALIFYING RUN.

2. It must have WON A RACE WITHIN 90m of today's race.

3. Must not be going back AT ALL in distance from the qualifying run.

4. Must not be carrying more than 1.5kg in excess of the weight actually carried in the
qualifying run.

5. Must have either: a) Won at today's track condition or b) Placed at least 30% of starts on today's track condition.

6. If today's prizemoney is more than $30,000 then the horse must have: a) Won at least 33% of the prizemoney of today's race or: b) Averaged $5,000 or more per career race start.

7. Do not consider Mares or Fillies in races open to male horses.

8. Do not consider a Welter run as a qualifying run for a Non Welter race today.

9. Do not consider a Non W.F.A race win for a W.F.A race today unless the horse has won a W.F.A race during the past year.

Thoughts?
