In Kevin's code (gyro.h, gyro.c) the time lapse between samples decided by programmer with a timer. If this interval (time) shorter, is the angular get more exactly?
You won't need to average before the integral because the integral acts like a very large average.

If the sample period (interval between samples) is shorter, the integral will be more exact. However, the sample period must be consistent from one sample to another.
