Bagman,
Boy you do go on [and on] with such waffle.

Even a progression of 1/1.5 [STOP! Start again] is a progression. The point of [Professor] Epstein and others, is: NO [not any] progression will turn a flat stakes loss into a profit and you go so far as to say your ladder progression will turn a -30% LOT into profit!
Like I said, Special Pleading rhetoric.

How about explaining why you haven't cleaned out every Casino in the World then, or does your progression system only work with Horse racing? Well why is that [oh boy, interesting reading for sure]? :-)

Perhaps you should lighten up on whatever you drink after Friday night Sybnagog...!
