Short version. Started using the speed sensor this weekend with the V 3.30 firmware, auto pause enabled. Unit would occasionally auto pause and then resume while riding. Happened on a couple of rides this weekend. On Sunday ride also noticed speed go to 0, then register erratically for a few seconds, then come back. Wide open, flat road, no power lines, etc. nearby. At first I thought it was an issue with the speed sensor. However.
Started looking at data from Sunday ride. Shows average speed of 17.7 mph, but average moving speed of 15.9 mph. Huh? Total time of 1:47:54, total moving time of 2:00:00. Huh? Went back and looked at some other rides. June 25 was first time I had an issue with my moving time being GREATER than my total time, and I believe that's right after I loaded the V 3.30 firmware. Issue has been consistent on every ride since then, I just didn't notice it until this weekend. Looking at data from yesterday and from a couple of shop rides where I know we took long breaks for new peeps, I suspect the unit is NOT auto pausing when stopped, even though it says it's paused. This is happening both with and without speed sensor connected, so don't think it's related to the speed sensor.
Turned auto pause off Sunday for the warm down ride home. Only about 3 miles, but avg moving speed slightly higher than avg speed, and moving time just slightly less than total time as you'd expect. Hoping to test it on a longer ride a little later this week.
