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

What exactly does 10% back/lay ratio mean, RP?
I hat eto ask dumb questions so I hope this is not one.

It is to do with the difference in price on the lay side to the back side. The closer they are the better. More than 10% different - no a good bet

Thanks Clive. My bot is not sophisticated enough to check for that but betting close to start time should take care of that.

The enemy of the Dutch backer, bot placed. If the spread between Back & Lay on one of your selections is say $14B ~ $20L and your bot tries to place a bet at $14 and it's not matched! It then goes SP, because of the wide price spread the SP could end up anywhere between the spread or even outside it. That's when you kiss your Dutch profit goodbye.
The tighter the spread, within say 10% the less you can get tilted! In Bhag's case he just didn't want the difference between actual probability of a win defined by Back odds and the odds you get as a layer to be too far away from reality. That's why I believe the long term profit is in Laying the 1st Fav. The difficulty is coming up with a set of filters to identify a false favourite across the board. It was easy to filter $30 + selections to identify potential winners. 1st Favs is still work in progress.
Sorry if I got you, Beton & LG in trouble yesterday, but I had a great laugh which is good for you!
My next project is to define how to grade filters in order of importance when you combine the filters of different selection methods?
Have a good night, RP

Just re read this and you might think I was the one who TOU'd you blokes, but I got TOU'd twice by someone with a hate on members having a laugh at the expense of no one. There was no flaming whatsoever, just a play on words. For all the positive contributions we make we are still not appreciated by some. What a dull place the forum will become.
This might be my last post as Sid Viscious will be hitting the button.
Bye RP

I did not know that I had been TOU'd. Our banter was on topic. And nobody was being got into as happens.
