Then I come across the 'caliper thread' here .. the all showing these "cute" pics of measured rubber. Breaks me up...

Why not some hard science? Measure air volumes .. wide vs narrow .. run on a machine and measure impacts. I mean something more than caliper calculus??
Read the dude's link this morn per rim/wheel stiffness... that sorta SOUND logic. San's a boney butt for the arbiter of ride quality.
Easily done .. if the real chore wasn't just peddlin' more components<<<
