nano fitness calibration not accurate
I have used my new iPod Nano with built in accelerometer 5 or 6 times now, and each time I have to recalibrate the run because it is so inaccurate...when I run 5k (a route that I have confirmed is 5K), it always tells me I have run much farther -- between 6.5 and 6.8K. How many times do I have to calibrate my run before it is finally accurate?
iPod nano, iOS 1.x
