This graph shows the mean values of the positive RC numbers in the depth of the shoe, according to the set strategy and card counting system. Positive RC means that only RC>0 values are considered and the mean value of these is displayed. The mean value of +RCs can be displayed in various breakdowns as well. You can conclude from the graph the expectable RC value at a certain part of the shoe observing only the positive RC numbers. E.g. you can see on the above graph that after dealing 21 cards the mean value of the +RC is 4, with the set card counting system, in one deck.
