Chris,
With the greatest courtesy -
1. I see no reason why Adobe couldn't have used 2 ICC profiles and
interpolated between them exactly like they do with the matrices.
2. I see no reason either the ICC or Adobe method should be
inherently "better".
Admitting the models are basically equivalent -if you assume you use twins- then
the real problem is how one determines the coeficients to get from raw
to color. Determining those coeficients is experimental technique and
algorithms. And there, I have so far seen no demonstration that you
have better color science or optimization technology than the rest of
us in this business.
