Actually funny you should say that. I will go back through my testing period and run the numbers for each way bets, 1 and 4 bets and 1 and 9 bets and see how they go.

I was using a staking plan of 2,2,3,3,4,6 for 20 units total per day. I found that 1 unit on each race actually gives a better % return overall. Strange. I guess because there has been 2 loss days in the 6 days I have tested to date and that wipes you out from your profit. I am also tracking 2% of bank. I will keep going with this as I think it should deliver over time. I will try to stop myself from applying filters as you said because a lot of the time the short price fav loses and gives you good returns on 3rd fav.

At this stage I have been looking as CLOSED favourites but really want to concentrate on 5mins prior as that is what I would be doing in the real world.

Is 5mins what you suggest Bhagwan?
