Ektar 100 shows the same exposure recommendations as Velvia 50 but is rated as ISO 100. I have gone as far as contacting Kodak about this but they offered no response other than they received my comment and would look into it. Probably too busy with looming bankruptcy issues at the time..... For what it's worth I find Ektar works better for me shot at ISO 64 or 50 but I only scan.
Now I see where you are coming from.

FWIW, Kodak's "Sunny 16" recommendations for Portra 160 are exactly the same, whereas their recommendations for Ektachrome E100G and E100GX are for one stop less exposure.

Their recommendations for metered exposures are to use the ISO speeds instead.

This tells me that the the "Sunny 16" recommendations are weighted to protect shadow details for negative films, and highlight details for transparency film.

Which makes a certain amount of sense, if you assume that correctly metered exposures are likely to be more accurate than "Sunny 16" exposures.
