I noticed that in 3.58 RobotC that
#define nGyroJitterRange 4
appears. I believe in 3.08 that this was 3.

Am I correct in assuming that this defines the A/D count dead zone of +_4 counts or about +_2.8 deg/sec.

BTW... my recent testing of a gyro shows a drift of about 6 deg/min even with this setting. Apparently my gyro must be very noisy. Our team has not been successful using the gyro to do the Sack Attack Programming Challenge purely autonomously. See post: http://vamfun.wordpress.com/2013/02/26/1508-lancerbots-reach-world-top-40-in-drive-skills-at-robodox-skills-challenge/

One of these days I hope Vex will give us a better scaled gyro to work with.
