It's purely a matter of doing it and seeing what works best for your.

I never got anywhere with the TPT. I couldn't feel the difference, and still can't. What I found was, as the razor got sharper, I could track its progress by how well it cut arm hair above the skin. Basically, the sharper it got, the higher I could go off the skin and the more smoothly the hair was cut. Moving up from 1K (shaving arm hair) I went on 4K until it cuts with a rough pop, with some pull. Then on to 8K until the pull is gone and the hair cuts cleanly and smoothly.

The problem is, my armhair test works for me because I've honed and shaved a lot--and I know the connection between my arm hair (very fine, but very thick and long) and how the razor shaves. Since your armhair is probably different from mine, you'll have to learn that correlation for yourself.

The same thing goes for the HHT and the TPT. You have to establish for yourself the connection between a shaving edge and any test you use. There's no fast and easy, one-shoe-fits-all test because everyone's face and hair are different.

It takes time to get that connection clear in your brain.
