OK, I'm still a little puzzled. You have a number of options for number of
points saved for a log, from pure "per seconds" recording, to allowing the
GPS to figure out how many points should be saved for a time interval (and
it tries, through averaging, to preen away points with little additional
information, while keeping a lot of points to define parts of the track with
lots of turns). I use an intermediate "automatic" setting, and generally
have no more than 2500 points in the active log after a convoluted, 9-hour
hike.

I would think that in downhill skiing, you would have fairly long periods of
few dramatic turns (the small turns will probably just be eaten up in the
noise), and the track might be well-defined with an automatic setting. Your
main "problem" will be the big discontinuities when you get on the lift.
