I'm not sure why you're so worked up. You are using HHT because it's faster than lathering. You are saying a variety of hairs is a plus and you have bagfuls of them to help you perform your test.
You're presenting the HHT as the ultimate test to tell you when you need to stop honing. Apparently you don't use it to tell you when to switch hones. Why? Perhaps it is because there is a faster test that tells you that and that's what you are using.
What if I tell you that some of the best honers I know use only the visual and tactile feedback of the honing stroke to know when the razor is not progressing any further and they are done honing. It's far simpler than what you are doing with multiple or special hairs.
You know what makes the experience in this post

And yes, Alan is among the best.
Now, if you need HHT to tell you when to stop honing what test do you use to tell you when to stop stropping? Have you considered performing that test during honing?
