I agree with you regarding the subjective nature of these things, which is why I've never made any bones about the fact that I think numerical gradations of a subjective test is not only ludicrous but, IMO, deliberately misleading the less experienced into thinking there is something scientific going on. And I will continue to poke fun at the hht-x wherever and whenever I see it arise.
Sorry I said the H word out loud, it was intended to be from one Coticuleer to another.

I will say this once, and never speak of it again here:
Numerical graduations of the HHT are, IMO, meaningful only to Coticule honing with slurry and slurry dilutions.
There is no doubt that keenness steadily improves during the dilution stage. This progression is intimately related to microconvexity, and the reason I invoked the H word.
As keenness improves, the force to cut a hair is reduced, by definition. (or at least by my definition of keenness)
When quantifying the HHT test we are attributing qualitative but repeatable characteristics of the manner in which the hair interacts with the blade to levels of keenness.
