I can see how the program may work great on a flat road, or a track. Doesnt do too well on regular streets. One thing that disappointed me is that it has to be recalibrated after every run. Suggestion: have an option of calibrating before moving, and have that setting stored during the whole use of the program. This way if you want to test 60-0 after 0-60, it knows your current speed and starts timing once the speed starts dropping below 60.
