Good feedback to riders needs, but

I love the Topeak mount for the IPhone. I dont train or race, and the info available is more than I need. The one aspect Id like, but cant seem to get is accurate grade of ascent or descent. The tutorial does nothing to address this and my attempts to correct have been for naught. Ill start on flat terrain and get a reading of 31° ascension. It would be nice if Topeak would address this or offer information in the tutorial on how to start your ride in a way that correctly sets the grade.
