The DART system.

FACT 1.
If all the money in a win pool was distributed as dividends,then throwing darts at a form guide to come up with a selection would be a break-even system.
If you can't acknowledge that,then read no further.Either go back to the start,or go away.

FACT 2.
But only 83% of the WIN POOL is refunded.
So the dart system will incur a loss of 17 cents for every dollar invested.
Not in every race,but the more races bet on,the closer the loss of 17 cents in the dollar will be realized.

So it seems the only,YES,the ONLY,way to profit from gambling the WIN pool is to cause the dart to be attracted more towards the potential winners and repelled from the potential losers.But even with a 17% sharper edge on your dart,you still only break even.

Well I'm going to sharpen my dart so pointy that the mug punters at the TAB are going to be too frightened to stand in front of me.
