This comment does not exactly address Roger's complaint, but it may
bear on its relevance. Even if we could achieve higher accuracy in
spectrophotometers, which is problematic for reasons that Robin and
Tom have outlined, let's remember that the standards we're talking
about here are not in the end spectrally-based, but VISUALLY-based.
So we're harnessing a lot of spectral measuring power to get the most
accurate conversion to L*a*b, LCH, XYZ, etc., all of which are based
on some thing far vaguer: the "average" human visual response. Does
anyone have figures for (deltaE) variability between THOSE instruments?
