0.392 degrees per second is
1411 degrees per hour. That's a bit more than 15 minutes per revolution, so your 5 minutes per revolution theoretically should be detected as about 2 or 3 counts.
Looking at it another way, 5 minutes per revolution is a little bit more than 1 degree per second. That's a little bit more than 12.5 millivolts, which again should be read as about 2 or 3 counts.
The people responding in this discussion forum are generally concerned with time frames measured in tens of seconds. I don't think many of us will have given a lot of thought to trying to measure angular rate over more than a minute or two.
