Here is our results of this test.

The tuner, as you can see, has 22 full turns.

Each turn has 24 clicks.

First shooting was one full turn out from a fully closed position.

Best results were gotten at 6 turns.

Then I shot 12 clicks either way from position 6.

That is what the 6 + X and 6 - x means.

No consistency at all.

It's hard to see if there is any pattern. I guess you could graph the results to visualize it better.

The results appear to be fairly random. It makes me wonder if any of this would even repeat if done again on another day?
