Well, before you get too lost in the technicalities there is a crucial big picture piece missing.

The fundamental part here is shaving, and I'm not quite sure you are yet at the point of being able to evaluate an edge and be within a standard deviation of a pool by say 10 of really well established honemeisters. That's as close as I think we can get to removing subjectivism from what a well shaving straight razor edge means (and of course you know the number ought to be at least 30, if we want to be scientific).

The technical experiments that you're setting up are nice because they're quantifiable and easy to understand. Yet the important point is not quantification, that's been done on industrial scale for over a century and we have plenty of commercially made razors as a result of that, (which you can study and rate scientifically, and you probably should start with that as a simpler test case).

I find shaving with any straight razor quite different than shaving with shavette, or feather, or DE, so even if you can prove you've gotten the sharpest edge out of a razor with numbers, I am still not willing to accept this as a well honed edge until I have shaved with it.

So, at some point you need to address the big question of correlation of numbers with actual shaving beyond the current simplicity.




BTW you should read that old paper of John Verhoeven et.al. if you haven't already.
