It would be nice if, along with the table of split times etc, that the Compare view provide a way to compare the graphs of the activities. Preferably having graphs of the same kind on the same chart, but even having them right next to each other would be better than nothing.
I would like this too.
Right now I have to export the two tcx files for the activities, then import them into Garmin Training Center, and use the compare feature there which shows excellent comparisons of all fields.
