Definitions

In plain terms

A 10% target divided by 20% measured volatility gives a raw multiplier of 0.5 before minimum and maximum limits.

Technical

The rule specifies target and measured-volatility units, estimator lag, floor for near-zero volatility, minimum and maximum exposure, rounding, and unavailable-state behavior.

Scope

It is a target exposure input, not a forecast or guaranteed risk outcome.
