I am starting to get a hold of it, it is really awesome.

BTW thanks for such an awesome application

I appreciate this in deep explanation, I just would like to know if there is a software I should use to be able to compare the lap maps. Kind of have them overlapped for quick visual comparison.
also can I display my line according to the track?

I am completely new to data acquisition, I would like to figure out how to read the GPS data(cvs) and compare different lap times.

thanks
