I've had an opportunity to measure reported tilt values of a Wacom Cintiq 12WX today. It wasn't a very precise measurement, but it still showed that the reported values are much likely to be *sines* of the angles and *not* *degrees*. This matches what Waltop Sirius is producing, which is quite expected, considering they seem to use the same pen technology. I've attached my data, along with an OpenOffice.org Calc spreadsheet containing a graph of angle fractions vs. sine fractions vs. fractions of reported values. I'm not sure what to do with this, yet. Sincerely, Nick
