I took a short run the other night. When done my 301 read 4.08 miles. Then MotionBased said 4.20 miles after uploading for a 2.9% difference. Which is more accurate?
nobody knows?
I think the motionbased version of the data is more accurate becasue it “pulls” more samples from the unit. -Not positive.
At any rate, I really like motionbased.com
