Hi, First, I would like to say I enjoy reading the forum so far. I have also read the NOR manual back and forth a few times. I am planning to go to the casino to perform paper betting practice (record the play and the bet I would make by using the NOR system) soon. If things are going go, I may play a couple shoes. I just want to practice to build my confidence as well as the intuition to select the appropriate system for the shoe. The question I have is regarding U1D2 M2. Let say the progression I am using is 123 4. In this case, if I lose 1, I would up 1 and got to 2. If I lose the 2, I would up 1 and go to 3. If I win 3, I would go down 2 and bet 1. What about the M2. I know is mandatory 2. But don't quite get it. The NOR manual mention it. But don't have an explanation and a betting sequence example. Would someone explain and put in a couple example. Thank you and keep up the forum. Dreamer
