Many books say to convert the hi lo running count to true count by dividing by the number of decks remaining. In the case where you have a high count and a surplus of high cards this appears to divide the cards between the remaining decks maybe 5 decks in a 6 deck shoe. However; these high cards may all be in the fifth, fourth, etc. deck or distributed some other way like in the first two decks,etc. Are there any studies showing that the cards do occur equally in all the remaining decks?
