My Garmin pauses at stop light, coffee stops, etc. It only records and measures rolling time, which can make a big difference. On group rides, I'm usually 15-16 mph, sometimes into the 17s. When I rode solo, my average is also around 14-15mph. Don't obsess over the speed, just ride more, and you will ride faster.
