By longest unbroken run

The longest stretch of consecutive years in which some registrar ranked the name, without a single year missing.

A year counts when any one of the seven registrars ranked the name that year, so a run can pass from one registrar to another. A break means no registrar ranked it that year — which usually means it fell below a published list's cut-off, never that no child received the name.
