I found this on a German website.



A combination of negative and positive progression on one EC.
Using 0.05 on BVNZ. We try it when we expect the wheel to produce series.






We try a longer parlay. 1,2,4,8,16. If we succeed we got 15 units plus or one lost.


If we lose the parlay we try again using 2,4,8,16. If we win we get 13 plus and start over.


On a loss we try using 4,8,16. If we win we got plus of 9 units and start all over.


We try the last time betting 8 units, and if we win we are 1 units plus.


A total loss is 15 units.




We could start with 15 on an EC got on NZ  50% chance of reaching the  win target. Something to
consider??


Here we have several trials, which is better??


I got luck and passed all parlay a few times, betting 15  once and use the series betting the method opposite may be
a option?


I won but I am not sure the method has more value compare to bet more at the first bet, and decrease the bets next time.
