Does any one know how to change the Pace average so the graph is smoother? The time the average is taken over is too short and the graph is very spikey.
I can't find any way to adjust this. I've been looking for the same thing. I seems to obvious a feature for Garmin to have made the 12 second averaging period user adjustable to as long as we want. But, alas, I haven't found any way to adjust it.
A work-around is to turn auto-lap on and set a short distance (I set 0.2 miles) for the lap distance. Then, configure either current lap time or last lap time for your display. If you pick last lap, it will show you the pace of the previous 0.2 mile segment. If you pick current lap, it will show you your average pace for the current 0.2 mile segment. At the very beginning of the lap segment, the pace might be little jittery, but after 30 seconds or so, it should be pretty steady as long as you don't have major GPS errors. The longer a distance you pick for auto-lap, the longer your averaging period is. This isn't quite the same thing as a true, continuous running average, but I haven't found anything better yet.
