Most of your variation is due to the fact that you were slower one day than the other! I had similar results when I used the function and saw the difference in the time as the cause. I also had altitude variations I couldn't explain though. Comparing routes should probably use location as a primary criteria and time secondary, but that is an extremely complex comparison to perform I would think.

On another note, they just released version 1.0.7 for winmo!
