Actually in the two clubs I belong to, the "ride average speed" is expressly defined the way you're talking about. So, say a flat B ride will "average" 17-20 mph, because that's how fast we're going most of the time, even though at the end of the ride, with warm-up, stop signs, turnaround, etc., our computers will read a true average more in the 15 mph range.
