Got to admit that all the "Target" betting plans I've come across would eventually go bust on that horror run IF you stuck it out to the bitter end.

But I think wesmip1 is introducing safety features in the sense that if a MAXIMUM bank is lost then start again with another bank, reluctantly accepting the loss, with the hope that even accounting for the lost bank(s) you still end up in front, ..... I KNOW that is possible over many thousands of bets over 3 years+ (cos I've done it) and yes I do think that is possible long term.
