Heres a plan I sighted

Target the Dozens sectors
We wait until one of them has had 7 outs before we start betting on it.
We start betting on that dozen with the 7 outs.
Units bet 1,2,3,4,6,9,14,21,32,47,71,106,159=475 for a run of 13 outs+ the 7 previous = 20 outs in a row would have to occure to do ones bank .
It is suggested to have at least 2 or 3 banks if one is going to follow this.

I have tested it & it does seems to work well , as long as one does not encounter 20 outs in a row.
I am not sure what the chances of 20 outs in a row would be , it would be interesting to find out if anyone has seen 20 outs of a Dozen section not getting up.

I would suggest a time limit of no more than 3 hours , then get the hell out of there before they gets your hard earned.
