I was not being verbose enough in my description. What you've said makes sense. Let me try to also make sense. 
The postulate here is that DE razor blades get uncomfortable for the person shaving, yet their measured sharpness only decreases by a small number of points. So what might account for that? I theorize that the blade is staying measurably sharp, yet is developing a more rough finish on the edge. It's sharpness is also decreasing, but not by that much. If the finish gets rougher, then the shaver is probably going to feel it.
My description of "denting" was probably not descriptive enough. What I mean is "roughening" of the edge finish due to impact with the stuff being cut: hair, skin, etc.
My theory might be wildly incorrect. As I said, I have no experimental evidence whatsoever. Well, other than noticing that my DE blades get dull when I use them. ...and that's not much of an observation.
