How the Site Handles Missing Data

Unavailable evidence is unknown. A failed request, a missing source, and a measured zero are different states.

Available inputs only

The numerator and denominator include available components. Coverage records which nominal weights were present. A completely unavailable score is null.

Stale data is disclosed

Source outages can lower confidence or prevent publication. They never insert replacement zeros. Short seasonality histories remain provisional.
