This troll needs more meat on its bones, so I'll feed it.
Many years ago, I was clocked on radar at a citizen's race as a last minute entry at 60 mph. I was wearing a parka and jeans. I stood straight up out of my tuck to kill speed before the radar spot because some curious spectator didn't believe there was a last minute entry and stepped into the course to look uphill and see for himself that I was on the way down. I had to slow to a level where I felt confident in dodging moving gates. I had a lot of confidence back then. 60 mph did indeed feel to me at the time very slow compared to speeds I had reached skiing cliffs on the back side of Mt. Washington BC.
Clink83 is right. If anyone really doesn't think a skier can ski faster if they don't have to make the gates, I have to wonder if they have a clue what they are talking about.
Data from Garmin GPSMap76CS track logs with 1 second recording:
First a typical day at Blue Mountain Collingwood, a relatively small vertical and no real steep runs, not really trying to do anything special, just put the GPS in my pocket and forgot about it and looked at the tracks later.
Next,a little experiment I did to see if the skis made much difference, comparing SG skis to SCs, trying to ski as fast as possible. No real difference in top speed, but speeds felt slow on the SGs and very fast on the SCs. I think the 82 mph is an aberation (it occurred immediately after landing some air and almost falling off the back side when the skis shot forwards), but fairly confident top speeds were over 60 mph. Mostly top speed is governed by air friction.
Another day at blue.
