The biggest flaw in the approach is that it relies on the GPS signal, and GPS is not that accurate itself. If you do not have a GPS signal, such as a [[Treadmill|treadmill ]] run, then there is no calibration possible and this utility will show that no calibration can be automatically performed. That is because the Garmin recorded data is based on the [[Footpod]], so it's calibrating the [[Footpod]] against itself.
