Where the figures come from
A dataset is planned around one question and a named set of source pages. When a page is read, the exact sentence that carries the number is saved, along with where and when we found it.
Each candidate sentence passes through review, and any rejection carries a written reason. The median and range count one figure per source, one per breakdown where a source gives several. Sources without a figure are marked rather than guessed, and regular re-reads track what moves.
