The start and the first two or three gates set the tone for the remainder of the course. Tucks probably don't contribute much.

OK now, this is a real question... no ball busting, really. My mountain uses the nastar course for our weekly ski school race, so I have spent a bit of time in it. I got registered and handicap'd? for a few runs because the mountain wanted me to have a baseline for possible pace setting or something, I dunno... anyways, I checked the site and I have five runs registered with a handicap of 15.11. Is this any good? I don't really know anything about how the system works. Does this mean i'm in the 15th percentile, or that I'm 15 seconds slower than god? It's always been my impression that a course as flat and straight as Nastar is faster on a flat ski, agreed? It all comes down to how good your push at the start is, how low your tuck is, and wax, right? That's at least my impression...
