We are at the top of the table, the territory of well-trained athletes and endurance specialists. Few candidates in any entry test get this far, and no official standard requires it.
This is the last published level of the table. Beyond it no official chart exists: an athlete who completes it has a MAS of at least 20 km/h, and the test cannot say more.
