I know, I saw the graphics, and I know that lost happen, slingshot in willhill starts with 0.1 euro, but to make a bet in such a short time, it is almost impossible for the higher levels of progression. For the tables with the dealer, you have more time, but larger limits. I think the minimum bankroll for this method is 5 times session bankroll, this is 15k units, because it can happen loss after loss.
