How often do we get each Running Count?

Unbalanced strategies like K-O, REKO, Red 7 and KISS use the running count for all decisions. Let’s start by looking at the frequency of running counts for K-O. Below, we see the percentage of hands dealt at each count using K-O for six decks, two decks, and single-deck with two and four players. We see a peak at -20 for six decks, -4 for two decks and 0 for single-deck. These are the initial running counts (IRCs) and the most common simply because you start with these counts. (Note: The REKO IRCs are slightly different.)

Since unbalanced counts tend to increase as the cards are dealt, you will see a greater number of counts to the right of the peaks than to the left. The range of counts is much larger as the number of decks used increases.

In single-deck we see a much narrower range of counts and higher peak at zero with an increase in the peak as the number of rounds decreases.
