I don't know if this is specific to my device or all FitBits in general but that's what I have consistently found since day 1. I'd rather it under report than overstate steps and distance.As for calories...meh...probably a vague estimation at best. I'm not as interested in those. I know it can vary widely by activity type.

Like basic pedometers before them, these newer devices can't calculate an accurate distance without first being programmed with an accurate length of your stride. Some higher end ones may use GPS for distance but GPS is typically not usable indoors and, even if you could get a GPS signal in a gym, I'm not sure it would work in the context of typical movements of a referee where distances moved might be a foot to the right then a foot back to the left. I'm not sure such subtle movement would register as movement at all with a GPS.
If yours, being used for straight line running, is always under the distance, then the stride length needs to be set to a higher value.
