Each row of the catch-up tables says "this closed record was matched by that open model, this many days later". This page lists every model that decides such a row, and for each one: its score on the selected ruler, whether AA measured or estimated it, which test items behind it were actually published, the archived page it was read from (with a sha256 of that file), and, where an item is missing, what a search of the rest of the archive turned up.
Click a row for its models. The bar shows how its neighbours' scores break down: measured, estimated with some items published, estimated with none, or no score.
