The following system, known as "The CD System", is really simple. You back any horse that is a previous course/distance winner in the race, provided there are no other previous course winners in the race. (It doesn't matter how many other distance winners there are in the race.)

No qualifiers.

Race 5: Rockford Bay UNPLACED ($15.00; no place betting)

Your so kind.. I'll add that to my stable. Do you think its advantagous to eliminate anything over say $12 ? Thanks

Have you got a DVD system too Glenno?

trust you sportz!

i might even think of burning this one - might be a keeper

There is no DVD System, since CD means "course/distance", not "compact disc".

Ummm, yes, I knew that Glenno. It was just a little attempt at humour. Obviously not a very good one.

Well, DVD could stand for Distance/Value/Days since last start. I'm sure we could make a system up out of that. How about this:
Races 1400m or longer.
Placed at last start no more than 7 days ago.
Must be $5 plus in pre post betting.
Must be only one qualifier in the race.

Have no idea how well that one would go, but it doesn't sound too bad for something I thought up in seconds.

Going on current commercial system prices should be worth around the $250 mark.
Probably work just as well as any of them.
What you require now is a bit of advertising.
The sort of thing like .
$300 to $300,000 in 3 weeks using 3 % of the bank etc etc.
Cheers.

For MSBA/Sat racing and using the Sportsman formguide, the results during the period 12/2/2005 to 5/3/2005 were as follows:

Selections: 14
Wins: 0 (0.00%)
Places (including wins): 4 (28.57%)
Place return: $10.60 (SuperTAB); $10.55 (SP)
Number of horses: 155 (9.03)
Number of winners: 14 (0.00%)
Expected number of winners: 1.6843

I have eliminated "win return", "relative frequency factor" and "actual-to-expected ratio" because there were no winners during the period.
