The average speed on my brand new edge 530 is showing at least 5kph higher than in reality.
I also noticed that the speed is correct during the activity but the duration seems to be off. Strava trims the file to put in a realistic average speed though so i assume the correct data is there but just sometime is off.
I assume there is an easy fix? All help appreciated.
File here (i think)
