90-100 feet per minute seems more like something that makes sense.
It's knots in gliders, or (I believe) m/sec on the continent. Good wave lift is powerful and very smooth - it's not uncommon in good conditions to see the needle on the stop. At 100 fpm it would have taken 80 minutes to climb 8,000', as it was the entire flight including aerotow & descent was about 50 minutes.
Of course what goes up must come down - the sink on the downwind edge of the wave bar is just as strong,
