The formula for stride length is weird and artificial. I'll have to figure my own and THEN figure how to work it into the gadget. IT might be accurate if I had the right formula I'll have to go to the track, count strides for 400 meters and divide. Then I'll need time to figure finally getting those buttons pushed in the right order to upload (or have a kid do it?)
So far, I'm not optimistic. This is a future shelf ornament, probably. To be fair, I gave it a 3--At least it runs and re-sets.
For those who just need to know steps and distance with out all the tech headaches. We wear them each week to track miles walked. Easy and battery last for several months.
