Method

Every figure on this page carries its source, its year and a link; figures from 2023 or older carry an amber mark. Route shares are modelled estimates on cited figures. The days in “Who runs short first” are read from the precomputed cases the network map and the scenario pages use; nothing is added across goods, late cargo is never added to lost cargo, and the EU (27) is never added to its members. The forecast box shows our register’s words and estimates unchanged, each scored when it resolves.
