These are the speeds for these films when subjected to the ISO testing regime. The speeds written on the box are nominal and reflect the stated developers and Kodak's regime for agitation etc. I have a friend who work in an independant ISO accredited laboratory that does standardisations and checks tests done by product manufacturers. Among the things they test are films. Why don't we all compare how we expose and develop superspeed film?
