Dave how accurate is that? Last I used GPS from cell phones it's just too innacurate because they aren't made for such precise measurements. Although, that was a couple years ago.

Right now I just put my video camera on, then click a stopwatch as I watch the laps. However, if and when I start fo reals racing, one of the final purchases on my list is a transponder..... Those can tell me my lap times right? I'm no Colin Edwards so I don't need to know within .002 seconds
