Some are reporting discrepancies between pedometer as measured by Neo vs. a real Pedometer. I am willing to bet distance is calculated by average gait distance based on height. So if you have a real pedometer or are able to measure the distance walked by GPS, try adjusting your height in the Neo pedometer and see what adjustment you have to make to get the distances to match. I bet the rest of us can use that to adjust our height to get a more accurate distance walked.
