Fred,

I haven't the data base to test this and the reason no one is punting their hand-up is PP odds data is rare as hens teeth. You could ask the moderate here if the system tester on sale includes them, but I doubt it will.

What I could suggest is the system will be a loser because of rule 4 [last start placings kill odds]. What would improve things dramatically would be: must have finished within 2 lengths of winner but must have placed 3rd. or worse.

Barrier position could even be left open, as the difference in win rates between BP is tiny, but the odds improve considerably with a wider barrier due to public perception [not fact]. You could even run this system with the rule: Must NOT be in barriers 1 to 7. The odds gained would outway any small barrier disadvantage. For the distances in the system, Flemington is a straight run and barrier position is meaningless.

Have a mess with the system and just try it out for small wagers or with no wager.
