Zone minutes tracking wildly off in workout - Inspire 3

[scorpjkt]

I'm having an issue of zone minutes not tracking correctly.  As you can see in the image, I did a 32 minute treadmill workout, and the app says I got 58 zone minutes.  

Unrelated, I'm having issues with the GPS tracking incorrect distances on runs even when connected properly.  For reference, I have GPS allowed in the app, and wait for the vibration to connect before starting.

These issues lead me to believe that my device is defective and I need to return it.  Is anybody else having these same issues?

Hi there, @scorpjkt. Welcome to the Community Forums. Thanks for the details provided in your post. I understand how you must be feeling. 

Please note that active zone minutes are earned based on your heart rate data. With that being said, bear in mind that heart-rate tracking can be affected by several factors including air temperature and device location on your arm For more information, see What factors can affect my heart-rate reading on my Fitbit device? You can learn more about how Fitbit tracks active zone minutes here: What are Active Zone Minutes or active minutes on my Fitbit device? 

About GPS tracking with Inspire 3, Fitbit devices calculate distance by multiplying your walking steps by your walking stride length and multiplying your running steps by your running stride length. We estimate your stride lengths using your height and sex. Track one or more runs using on-board or connected GPS, we evaluate that data to automatically update your running stride length. For best results, run at a comfortable pace for at least 10 minutes.

If you prefer to measure your walking and running stride lengths yourself and enter them manually, see How do I measure and adjust my stride length?

Note that when you're tracking an activity with GPS, Fitbit calculates your distance using GPS data rather than steps. If you begin moving before you get a GPS signal, the tracker will calculate distance using steps and stride length as described above until a GPS signal is found. In this scenario, your total distance calculated for the workout may be slightly less accurate than if GPS data were available for the entire duration. For more information, see How accurate is GPS?

After reviewing this factors, please go for another run and see if the distance improves.

Hope this helps.
