Wrong Average Speed
problem

Sent you an email with the details. seems that the average speed is wrong.

I think you are averaging the sample points (where many of them are 0 for some reason).
while the empty samples are a problem by itself (all location data and lateral data are always full), it should not affect the summary data.
A simple V=D/T on the lap data will provide a better solution.

This may indicates a GPS issue with your phone. If Trackmaster detects an unrealistic speed, then it will default to 0 MPH. This will also affect the acceleration computation. If you provide your data in Google Earth format, that should provide a quick answer if this is the issue. In the next version of Trackmaster, there will be some improvements to compensate for these inaccuracies with the internal phone GPS.
