Good Evening. I am using KO and Wonging in at plus 2 or better and Wonging out at plus 1 or worse, so I am not making any bets in negative ev. Maybe this is a bad way to do it but if the count is say plus 2 and I bet 1 unit and lose, I will bet two units the next time if the count remains at least the same or better. I will do this again, 4 units, if the count remains plus two or better. Four being the top limit bet. This is on single deck. So far I have had good success. It seems to have a better result than 1 unit at plus 2, and 2 units at plus 3, and 4 units at plus 4.
