AOII confusion

I'm currently reading Bryce Carlsons Blackjack For Blood with a view to upgrading to AOII in the near future. Problem is, I'm finding his description of the true count somewhat confusing.

He seems to state in his book that all true counts are arrived at by division, page 78:

"For instance, in a four deck game, with a running count of +6 and three decks remaining to be played, the true count is:

True Count = (+6)/(3) = +2

Or in a single-deck game, with a running count of -5 and one fourth of the deck remaining to be played, the true count is:

True Count = (-5)/(.25) = -20".

Now, both those examples are accurate enough but no where in his book can I find mention of multiplying plus running counts in single-deck games. For example, according to what Ive read, a running count of +10 at the half deck level would divide to a true count of +5.

This is backward to the way Ive been doing it, where the above example would multiply(*2) to a true count of +20. Yet, I havn't found where in the book Carlson makes mention of multiplication of plus counts.

One of three things can be occuring here:

1. Ive missed or miss-interpreted something in the text.

2. Carlson has made a glaring error.

3. There is no multiplication of running counts with AOII in single-deck games. Therefore, a true plus count is always smaller than the running count.

I'm sure that 3 cant be the case. Can someone who has read Carlsons book key me in on what I might have missed.

I don't need to re-read Carlson's book to give you the answer. It is simple math. With half a deck remaining on a single deck, you can either multiply by 2 or divide by 0.5. It is the same thing, mathematically.

(+10 rc)/0.5 = (+10 rc)/(1/2) = (+10 rc)*2 = +20 tc

Yeah, Ive got it. I have to say that(for a non mathematician) it is a very confusing way of describing true count calculation. Richard Canfield gets it across so much clearer in his book(for non math guys anyway).

Thanks for the response. When I learn Carlsons system I intend to calculate true counts in single-deck games to the following criteria:

First quarter of full deck: RC and TC are the same.
Second quarter of deck: Multiply/divide RC by 1.5.
Third quarter of deck: Multiply/divide RC by 2.
Fourth quarter of deck: Multiply/divide RC by 4.

I'd appreciate your thoughts on whether the above scheme is accurate for AOII.

SD Player.

3/4 deck remaining = rc + 1/3 (or x 1 1/3)
2/3 deck remaining = rc + 1/2 (or x 1 1/2)
1/2 deck remaining = rc x 2
1/3 deck remaining = rc x 3
1/4 deck remaining = rc x 4

Ive remembered that true count conversions in single deck are essentially all multiplication. I.E. a true count of +10 at half deck level multiplies to a true count of +20(*2). A true count of -10 at half deck level multiplies to a true count of -20(-10 multiplied by 2) and is therefore an even smaller number after the sum.

I thought that division was only applied to multiple decks. Carlsons use of division in single deck-games threw me off. I knew it had to be something I'd miss-interpreted in the text.

Wily, your system of calculating true counts in single-deck games is very sophisticated but I'd rather stick to quarter deck divisions. It would take a great deal of experience to calculate the deck to your standards. Thanks for answering.

I think this thread has been cleared up.
