Don't know if it was THAT funny K909, what Mr J had to say. Anyway I'm of the opinion (maybe wrong) that the "edge" is to beat anyone playing level stakes (over time) and to simultaneously stop people playing all the numbers/both sides of the colours etc to their advantage. The "limit" is the casino's second line of defence, specifically to stop progression systems.
Mr J. Your first post in this thread was to do with progressions. That's the only reason I mentioned them.Cheers.
