Movement duration statistics

[nsuprin]

Hello Everyone,
It should be a great improvement to be able to get the informations about the movement duration.
In many GPX files, we can observe some time gap wich are often a real pause for the persons wich are recording the track on the terrain.
And today, the duration is simply calculated by a diff between last point timestamp and first point timestamp.
So the avgSpeed and Pacce are impacted negativly.
It should be more accurate to distinguish the global duration, and the movement only duration.
