There's more than one way to compute distance, and some methods are more prone to roundoff error over small distances, which is relevant for tracklogs. My code is at http://www.aigeek.com/geophoto/ and more about distance formulas are in the Wikipedia: http://en.wikipedia.org/wiki/Great-circle_distance I have some python code that deals with GPX tracklogs and does various things, including distance computation.
