I thought I'd blow the dust of some oldies but goodies today, seeing as I've got 3 bots now. Got to find work for them.
This system dates back to 1st April 2011.
RULES
Target 4th-7th Favs (now I've just done 4th-6th today due to bot limitations)

Lay price $10 - $11 BF exchange

5 secs to jump

10% Back/Lay ratio

7 - 23 runners

Now Bhag's used this system on Aus Races + trots, UK & USA races. He claimed that he made 28% a week. he used a Lay88 staking plan.

Well no need for the staking plan today a perfect score of 10 selections, 10 smiles. A POS (Total profit/original stake)*100 of 93.76%.

Give it a try, RP
