The time it takes to scan the gyroscope, compute the data, and display the results has a bearing on how far it has drifted in that time. One millisecond was more than enough to show visible drift. I set up min and max variables so I could measure the extremes of continuous scan times. My results showed that I was looking at 8-25mS, but I also found that it took 3mS to query the gyroscope, and I wasn't factoring that into my calculations. I subtracted 3mS from each wait period, and that helped stabilize my readings during rest periods, but there were still a lot of jitters.

I let the device sit on a table while I recorded how much it would drift in one minute. The first series of experiments used the -3mS on each period and the second set used -2mS, and I found that the readings would drift by as much as fifty degrees in one minute. Some of the results were more stable with as few as seven degrees, but in one minute, there should hardly be any. More work is needed.
Precise but inaccurate
