Guys when I concocted that jitter test, I knew that the biggest problem with the test is the human input. So I tried my best to draw at same speed between two machines. But even with that, it's not super reliable due to speeding up and slowing down while drawing to meet my 6 second duration I gave myself. I also tried to keep the pressure level constant but that was undoubtedly variable between tries, and I do think that also somehow effects number of nodes. What I'm saying is, it might be problematic comparing input between 2 different people on 2 different digitizers, even if the duration and length is the same. I think a much better test would be somehow being able to see the digitizer grid and photograph it against a ruler. I know that some MPP digitizer in bright sunlight can reflect the digitizer grid to naked eyes. I would hope that all the pro cap digitizers since they rest on the surface of the glass can be visible in certain lighting and can be photographed. I think we as a community should investigate methods to make the digitizer grid visible easily.
