Are missing months filled with old values?
Missing measured months remain missing; review examples are kept separate from measured history.
Method and interpretation
Align metric definitions, denominators, question sets and conditions before comparing months. Distinguish the report publication month from the analyzed month, and do not fill missing periods with inferred performance. Rate changes use percentage points; progress toward a target uses attainment.
