From the Home page:

Tools | Track Log | Menu | Setup | Track Interval

gives you the options of:
  • Automatic
  • Time (with a user-settable time step)
  • Distance (with a user-settable distance step)

I believe the GPX format just stores a list of Height/Lat/Lon/Time quartets,
and doesn't care about any frequency.

I have always used "Automatic", and the step size typically varies from 15 seconds when I am flying straight to 4 seconds when I am turning.
