You could make this progression like the star system.
(must win twice on any level to revert to base bet)
 
Example:

1
1
2
2
4
4
8
8
16
16
stop

recovery 1
2
2
4

8

recovery 2

Loss of daily bankroll at this point.

Using the progression this way you could have 30 straight 
losses in a row versus 21 for the star with about 55% of 
the required bankroll of the star. As far as a lost double 
or split you jump up two levels instead of 1 just like the 
star. The star system is very good but it is hard to find 
table limits that will accept it. This would work very nicely 
in the $5 to $500 tables.
