|The ability to carve should be developed by first skiing a line that is more round. Once a racer can successfully carve turns in this line, he or she should gradually work on tightening the line, without sacrificing the carving action of the ski. (Of course, even at the World Cup level, a clean carve does not always happen, but it should be the ultimate goal of any athlete and coach.)
A common mistake made by coaches and racers occurs when a young racer tries to tighten his or her line without correcting the technical errors that prevented him or her from carving turns and skiing fast in the first place.
Though these technical errors can vary for every racer, several of the most common are:
Do we maintain our bad habits in one sport and the other?
Do we train bad skiing habits as we skate well?
FWIW, I would expect anyone ticking the bottom three boxes to
a) be able to skate in the rain
b) be able to make round turns down steep hills on skates
