A couple of things:

  1. Welcome to SRP!
  2. You shouldn't have started over from scratch using the dilucot method
  3. If it came shaving sharp, you should have just done 30-40 laps on water only with no pressure, and that would have almost certainly brought the edge back.
  4. Since your dilucot attempt failed, I'd bail out and do a unicot
  5. HHT is not useless, and it's not a parlor trick... IF you calibrate it to something that's meaningful to you (ie, take a razor that you know shaves well, and play with the test and a consistent hair source so you can make it meaningful to you)
