How about a dynamic handicap? Using the logger files, you could evaluate
not only the wind profile, but also the strenght and diameter of
thermals and their separation, cloud base, etc. etc. and apply not a
handicap number, but rather a handycap matrix which is fair for all
gliders in all conditions. And don't forget to define a pilot factor as
well, otherwise the experienced ones would have an unfair advantage!

You know that you have your parameters and the formula correct when,
after normalizing the results, everybody gets 1000 points.
