I noticed that the total Elevation gains would vary some for a run which has almost exactly 190' of ascent. One run would say 129.' The other would say 154'. Had another say 168' - same exact three runs. So, I went to Garmin Connect and looked at the elevation graph. I hand calculated the climbs using its elevations. They matched and were accurate to roughly 190'. So the graph is accurate but the total listed for the activity is accurate. Any way to fix this(graph on Connect does not match the total elevation gain for an activity) or is this just an issue since the watch does not have an altimeter?
