How do different manners of True Counting differ?

There exist different methods of calculating a true count. (This page will not be of interest to running-count players.) You can estimate the remaining decks in different manners, round the results differently, or include or exclude cards on the table among other variations. We will look at a couple of these variations here.

First, we must estimate the number of remaining cards. This chart shows three levels of accuracy in this estimate: remaining cards estimated to the nearest full decks, half decks, or exact cards. All data are based on six decks. The blue line indicates an exact calculation of cards in the discard tray (not counting the cards on the table). As you can see the higher the accuracy, the higher the advantage at high counts. These counts generally occur late in the shoe where accuracy is more important. However, the important counts are +1 through +5 as this is where most of the money is bet. At these counts there is not a large difference. Therefore the overall gain in better accuracy is not that high unless the penetration is very deep.

Charts on overall gain by penetration are available later in this chapter.
