Mike.
Here is a simple plan that throws up a 36% SR targeting min price $2.80+

.Target all Pre-Post race Favs

.List all the Favs prices.

.Bet the 2 horses with the 2 shortest price.

.We will end up with 2 horses per venue.

.Do the same for all venues .

. Bet .5% of bank level stakes , adjusted up & down daily.
e.g. $1 / $200 ratio

Take the advice about obtaining best price because you wont get it just using one TAB account.

This plan shows a profit using Betfair targeting a min price of $2.80+.

If just using your local TAB you will be lucky to break even, that's how much the price difference is between the two agencies.

Try & only bet if one can get $2.80+ if possible. Otherwise no bet.

Betbotpro
One can use a tool called Betbotpro to place the bets for you on Betfair at say 15 secs till jump time ,at say a price of 2.80-11.00
Its a Robot that does your betting for you, while you are at work & it is very accurate & simple to use.
It can have stop losses set & max profit set.
It even has its own forum for its members only.

Bets can be as low as .10c

I use this & its a fantastic tool to use , especially if one does not wish to be in front of their PC all day.

It also has a choice of staking plans for win & lay betting.
Comes with a free trial that can be run in simulation mode on the overseas races.

It even has a program that will only place a Lay bet if its Lay price is within 10% of the Back price . (Adjustable percentage)
This stops the program placing a Lay bet that maybe 12.00 where its Back price may be 6.00, very powerful tool.

Covers all countries Dogs , Trots, Horses.

One could literally bet 24 hours a day ,7 days a week.

It is a must have for time saving & value seeking.

Ask yourself a serious question.
Could you honestly sit in front of the PC & let 12 races go bye, before placing a qualifying bet which may present itself.
Betbotpro can & do it 24/7.

Cheers.
