Frequently Asked Questions
Is this a gambling recommendation?
No. This tool is strictly for educational analysis of advantage-play theory and probability concepts. It does not guarantee any outcome, and actual results depend heavily on variance, rule variations, and casino countermeasures.
What is a bet spread?
A bet spread is the ratio between your minimum and maximum bet sizes, used in count-based strategy theory to size wagers relative to estimated edge.
Why is my expected value so small relative to variance?
Advantage-play theory typically produces a small edge with high variance, meaning short-term results can differ enormously from the long-run theoretical expectation shown here.
