Mathematics

The probability engine

CountVision does not use a fixed lookup table alone. It recomputes the dealer outcome distribution from the cards that actually remain in the shoe, then compares the expected value of each available action.

What is calculated

Probability of busting if you hit
Probability of drawing selected card-value categories
Estimated dealer bust probability
Estimated win, loss and push probabilities
Expected value of each available action
Difference between the best and second-best decision
Recognition confidence

Close decisions

When two actions have similar expected values, the recommendation is labelled a close decision rather than presented as certainty. The margin is always shown.

Decision inputs

Player hand composition
Dealer up-card
Hard, soft or paired hand
Table rules
Cards remaining
True count
Basic strategy
Count-based deviations
Comparative expected value

Educational estimates

Probabilities are educational estimates. They do not guarantee a particular card, outcome or financial result.
