I my opinion, how anyone else rates a film is pretty much irrelvant.
I start at the recommendation and experiment from there.

As for people systematically overexposing Velvia, furrfu, if
they don't like high contrast and mega saturation, why are they paying
$15 a roll for the stuff? Snob value?

There's a school of thought that "All manufacturers lie their ass off
about speed for marketing purposes". The same people probably keep
their film in a pyramid so it lasts longer.
Anyway if Kodak had told the truth about film speed, the Zapruder film
would have been clear enough to show that Badge Man was Elvis with a
CIA isssue laser pulse rifle.

Hallelujah! Hear the word!
