Tracker Distance in "Get Daily Activity Summary” for the FitBit Flex

[alexbadut]

Hi, 
We are using the FitBit API to reward customers with points based on their runs. 

While using the Get Daily Activity Summary endpoint we discovered that for FitBit Flex one user the tracker-distance has very different values compared to the sum of the distances for the logged activities.

Is it the case that the distance value for the FitBit Everyday products (Zip, One, Flex, Charge) is not reported accurately via the API, provided the devices limitations?
Would highly appreciate some help.

@alexbadut That's because those are taking distance from two different things. One is taking the distance recorded by the tracker, the other is only taking distance from manually logged activities. You might want to use 'total' distance.

@AndrewFitbit thank you for your answer. 

In our case, the tracker distance should be comparable to the logged distance, provided the user has used the track exercise in the FitBit mobile application in order to register a run. The active minutes registered by the tracker are comparable to the logged run, but the distance is very far off (for about 47 very active minutes, we get a tracker distance of 0.2).
