I have used both and I've only noticed people ask about stride length. That is fine in my experience. What I have noticed is using the Treadmill option, I walked 1.5 miles at pace of about 2.9 mph average, it logs it as a run at 5.0 mph. The walking option, while getting it closer, still logged it as a walk at 3.5 mph.
My first question is what are the differences between the two? I mean which one should we use for logging walking on a treadmill?
The next question would be, why does it record the mph correctly, but title it as something faster than it was?
Thanks for the input!
