Gurshman himself goes through great lengths describing outside/inside ski weight distribution, and it is never 100%-0% at the points shown by track 3. At the point in which track 3 starts, the weight distribution in a realistic turn ought to be 70/30 or even 60/40.
Track 3 is not "the best one" as you said. Track 2 is a far better example.
He first identifies the weight distribution that current teaching methods use to getting to track 2, ( RRX of track 1 ). Then he shows what the weight distribution in a real turn is like (eg. track 2). Then he suggests an exercise to learn how to create those tracks, which leaves tracks similar to track 3. Nothing at all like railroad tracks.
His paper clearly highlights the deficiencies in using rail road tracks to teach the role of the inside ski in arc-to-arc skiing.
Hey, so I misspoke. My Russian is rusty since I left MI6. Your analysis is correct. Glad to see someone studying what GG has to say since he's pretty up on what's going on out there.
Gurshman does, though, say: "Usually the turn begins above the fall line of the slope with almost 90% of pressure on external ski."
He also goes on to say that:
If we attentively study some WC leaders' techniques, it is possible to note that they slightly raise the inside ski at the entrance of the turn. It goes without saying, that in this case the athletes enter the turn with the relationship of pressure of 100% on the external to zero on inside ski. This substantially helps to avoid obstruction to the inside ski in the first phase of the turn. A similar technique is characteristic of athletes of the older generation of such as, for example, Eberharter, Ammodt and Maier. From childhood of maturity they were taught to raise their inside ski & they continue to use this method in combination with the new skis. However, younger athletes, who mastered contemporary technology at the junior level, attempt to hold both skis in the fixed contact with the snow, which, with other conditions being equal, leads to the smoother cutting of arcs and speed. Specifically, this technique should be taught to juniors, but we shouldn't disregard the operating techniques of experienced athletes.
So, example three is not, as you say, "Example 3 is the tracks left by an exercise -- it is not the "right" way to ski. They are left when trying to learn how to use the inside ski." They are tracks left by some well known winners on the WC.
Anyway, Merry Christmas.
