The longest run of outs one should experience is approx 11.

A staking plan that can work with this is the Duel Progression Plan .
It can be used for place & EW betting also.
Use the search bar at the top to find it.

It goes something like this .
1L 1L 2L 2L 3L 3P 5P 7P 9L 9L 10L 10P 12P 14 ect.

Until in profit, then start again.

Cheers.
