Data in fit and gpx files with same activity are different

When you save an activity with both fit and gpx output format, the data when view in the GPSr are slightly different, such as Distance, Ascent-Total, Descent-Total, Min-Elevation, Max-Elevation .... etc.
If you use the fit file and save as track, then the data in this gpx file would be the same as the fit file.
Further explorer to these two gpx files with notepad and found that, the gpx file saved by fit file includes an additional statement - "TrackStatsExtension" like the following:
Other than that, the data recorded in these two gpx file are same
The GPSr or other applications seems to use the data in this statement instead of by calculation of the recorded data.
Don't know which one is more accurate.
