Inaccurate Distances

[debiwiedekamp]

My friend got a new versa 2 ad now our walks are totally messed up. Her pace is 20 and mine is as always, 17. I’ll have 3 miles at the appropriate time and she’s .40 behind on her distance. We can’t figure it out.

Hi there @debiwiedekamp. Welcome to Community Forums.

I understand how you feel about this. Fitbit devices calculate distance based on the device’s accelerometer data and stride length setting. Default stride length is based on your height and gender. If available, Fitbit devices use GPS data to calculate more precise distances. When you sync your device, our algorithm interprets the data from the device, and you can see your distance traveled in the Fitbit app. 

Note that when you track an exercise with GPS, both GPS and accelerometer data are used to calculate the distance shown in the Fitbit app.

I'd recommend you check these articles, How does my Fitbit device calculate my daily activity? and How accurate are Fitbit devices?

Hope this helps.
