Brief Comments
There really are two Revere Advanced Point Counts. One is called the 14-Count because the sum of the count values for low cards is 14. The other count includes the ace and has a sum of count values for low cards of 17. Both are balanced counts.
The true count divisor for both of the above counts is the number of half-decks remaining. The true count divisor for the High-Low Count is the number of full decks remaining. Each High-Low true count is worth about 0.5%. A typical game has a house advantage of about 0.5%, perhaps a little more with worsening rules. Therefore, a a High-Low true count of +2, the player has an advantage of nearly 0.5%.
The sum of the count values for low cards with High-Low is 5. Therefore, the value of each true count point for the 14 Count would be about (5/14) � 0.5 = 0.18% and the value of each true count point for the 14 Count would be about (5/17) � 0.5 = 0.15%, if the true count divisor were the number of full decks remaining. These numbers must be multiplied by 2 because the true count divisor were the number of half-decks remaining, i.e. they are about 0.36% and about 0.30%.
The Revere Advanced Point Counts are extremely difficult to use. Revere's playing indices were calculated more than forty years ago. Modern software, e.g. QFIT's CV-Data, probably produce more accurate index numbers.
