US rules had "windicapping" as part of the rules a few years ago. This
was based upon logic that wind is the largest variable that a single
handicap number can't deal with.
It was in place for a couple years and never really got used, so it was
dropped. It definitely slows down the whole scoring process and would
make the scoring program much more complex.
It is of some significance that in order to get the scoring program
guys to do this we would likely have to get them very drunk for a very
long time.

IMVHO the reason windicapping was not used was due to flawed implementation.
A PST first turnpoint could have been disallowed as less than the minimum
distance when windicapping was applied. The pilot while in flight would
have no easy way of discerning this. In fact, while scoring Region 9 a few
years ago I had to toss windicapping for exactly this reason.
