Bah, I'm in late at work trying to get the data I need. It's not even real data, just calibration data. Nor does it help that I started looking in the wrong place, but that's why you do calibration runs: to make sure you're using the right parameters.
If one in two runs works, then I will be out of here in time for volleyball. Unfortunately only about 1 in 3 is currently working out. Bugger.
