An angle that seems to work well using this idea is to use this staking plan bolting 2 venes together.
That way if one venue is a dud the other usually producers one or more results.

Do this in lots of 2 venues each time rather than using it right accross the board.
It usually minimises the outlays to risk as well.

Check it out using 2 venues at a time for each bet sequenc.

If there are 8 venues on the day , one could have 4 batches of 2 for each bet sequence.

Try & remember to stop betting if 9 outs in a row is struck then recommence once a winner finally gets up.

I feel this idea would work best using say the IAS bookie prices that way one knows what the price is going to be once the bet is place.

Cheers.
