unless you 2 are exactly the same height and stride distance.. that estimate ie totaly off.. im 5'7" and 4 mph is a jog for for me.. 2,5-3mph is a brisk walk. If you dont want to repair it, i would go to a gym.. set certain speed levels and see how many steps per min it is on your pedo and work from there.
