Again, the really bizarre thing is that I only have this issue walking moderately fast. I just came back from a 6 mile run over the course of which my Force, Loop, and Runtastic Pedometer logged 10,265, 9,102, and 10,366 steps respectively. Proof that none of them are perfect but close enough for government work and in a reasonable step length range of 37" to 42". On previous run tests, the Force and Loop were consistently within 1% of each other so I'm not sure what happened today.
I understand that an activity monitor's basic function is to SWAG your general activity level rather than precisely counting your steps but Fitbit insists that their products are accurate to within 5% and I'm consistently getting under counts of well over 30% at precisely the speed most people would walk for fitness. Also, this is not logical and my inquiring mind is demanding an explanation. That, quite frankly, is more important to me than a pedometer that works :).
