Uh oh. Next problem. If thermals don't drift at the same speed as
the wind, how accurate is that wind speed your computer derrives from
drift while you are thermalling?

My experience with a 302 and SeeYou Mobile was the differences were
small compared to other variations due to time, location, and altitude,
and small enough that I usually didn't notice any difference. But, there
may be places that do have bigger differences, and I just didn't fly there.
