Juvenis have two different tables in one season
This is the piece nobody explains. Juvenis swimmers face two national TACs for the same event: one for the March championship and a harder one for July, on the reasoning that swimmers are expected to be faster by summer. In the 100 Livres long course that's 1:01.25 for March and 1:00.19 for July — just over a second, and the difference between qualifying for March alone and earning both championships, including Jamor in July. Infantis have a single July national table, and their own February zonal.
