Well, if I understand you properly, then Verichrome Pan and Tri-X Pan are identical in DK-50 at all temperatures, but are quite different in HC-110B at all temperatures. And, as you point out, since the wheel is non-linear the temperature response is the same in DK-50 but quite different in HC-110B. But look at the post above by D. F. Cardwell if you don't believe me. That is some pretty good data! I have similar Kodak plots.
