How would you be able to accurately measure it if you dont do it from a standstill? Your jerking all around when moving and it only uses the accelerometer to measure the power. So any slight movements and it will throw it off
Well, they could use iphone GPS to record initial speed, but then those who have one know how accurate the iphone GPS is...
