15 further amendments in these titles carry no part identifier and cannot be attributed to a specific scope, so they are excluded from the chart rather than assigned to one.
Attribution is exact, not estimated: each scope is expanded to the set of parts inside it in the current structure, and only amendments to those parts are counted. Dated by issue date, not amendment date — the two differ in about half of all rows.
