Uston APC
Ken Uston’s level-three ace-neutral count from Million Dollar Blackjack (1981). Aces are 0 in the primary count; published APC uses an ace side count for betting.
The values
How the values work
Ken Uston published the Advanced Point Count in Million Dollar Blackjack (1981). It is ace-neutral and level three: fives are +3, tens are −3. The primary count does not include aces. Uston’s published use of APC keeps an ace side count for betting.
The app flag for this system is that it requires an ace side count — not that aces are tagged in the running count.

The ace side count
Ace side count
Published practiceAces are 0 in the Advanced Point Count. Uston’s published APC keeps an ace side count for betting. The running count never scores an ace.
Tally aces as they leave the shoe. Remaining aces versus remaining decks tells you when to raise the bet. The primary true count still drives playing deviations.
The math
Running count, then true count
Start at zero
Balanced. Start at 0. Aces do not move the running count.
True count is running count divided by remaining decks. Keep the ace side count for bet sizing.
Efficiency
Why the numbers look like that
Level three shows up as PE and IC. Primary-count BC still assumes you add the ace side count for betting.
