Distance Discrepencies

[abrad]

The distance values that are returned for both single-daily GET activities/DATE requests and time series GET activities/distance/date/DATE/max.json are inconsistent with the values shown on my fitbit dashboard. Which values is the dashboard displaying, and how do I get access to them? Why are the values returned by these endpoints so inaccurate?

I believe the difference may be manual activities. 

Badges and lifetime stats -- and I think dashboard values -- are based solely on data collected by the tracker device itself and excludes logged activities.  You can get these values by inserting the word tracker, e.g.

activities/tracker/steps  (instead of activities/steps in the API call )

See the descriptions at API-Get-Time-Series

The tracker specific calls are also giving me distance values inconsistent with the dashboard.
However, the request for steps returns consistent data.
