If interested in the effect of aerodynamics and how coaching it effects other things, perhaps you will like this recorded webinar from february:

Lots of similar webinars on the same place. Just sad that the imbedded videos often are very choppy.
I was gate juge at a kids race earlier this year. Two times 80 min with 10 min break in between, wind at times blowing so hard that it would threaten to steal the start list or worse the gate jugde card every time I had to take it out to make notes. A joy ;-)
Watching just 4 gates for almost 3 hours on a very flat and easy hill. Was starting to wonder what's the point, if it's a contest in having parents good at waxing, beeing lucky with the wind or beeing shaped mostly like a plug. But watching the fastest few, it was really apparent that they solved it differently ski technique wise.
Even at this easy section the best where able to ski ski really dynamically. Not supporting their weigth in-between turns but letting it flow undisrupted from turn to turn.
The trajectory of their COM in both in terms of up/down and direction decided in how they ended the last turn, and not having to interfere or support it before close to the apex of the next turn. Perfectly mathing the dynamics of their ski turn with the demands of the course without any "dead spots".
Hope I get as good as the those best U12's before I stagnate out of age related reasons ;-)
