Modeled survival band

Part of Simulation outputs in the PropSurvival glossary — defined the way the engine actually measures it.

A range, not a pointModeled survival band

The risk-per-trade range where modeled failure probability stays within tolerance without starving the pass rate. Shown as a band, not a point, because live execution never holds a constant. It is a model output, not a safety guarantee — no risk level is safe, and this one is only as representative as the inputs you gave it. (Earlier releases called this the “safe risk band”; the name changed because “safe” overstated what the number does.)risk range where modeled P(fail) ≤ tolerance · measured: risk size against a live floor
