Good articale David, I couldn't agree more.
p.s. more Pt in the Pt/Pd mix will change the tone (more neutral black),
change the speed (lower speed), change the contrast (more contrast), and
sometimes add a bit more grain.

Although the Pt/Pd mixes does cause those 4 changes don't you feel the main
change is in the tonal area and is the reason to use more or less Pt.. Seems
the others are really more byproducts of the PT/Pd relationship.
