Common comparison error

Demo execution included in Variance cannot establish live payout, latency, withdrawal, or Loss limit behavior.

Practical use

How to verify Variance

Read Variance together with Expected value, Loss limit, Affordability. The comparison must preserve the exact rule, value, state, and evidence described below.

A neutral example

A strong Variance weakens when payout falls from 85% to 70%. Reporting both cases prevents the selected rate from hiding its effect on Expected value. The evidence must resolve the defining Variance boundary: outcomes with the same mean can have materially different dispersion and loss sequences.

Evidence path

Where to verify Variance

Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
