Here is a perfect comparison of the difference between flexing and retracting the outside leg to release compared to a push or extension release. The follower is a good skier, but his technique is completely opposite to the skier in front.
The retraction release gives the skier earlier angles into the next arc and a progressive edge engagement. I've been advocating this approach for these very reasons in PMTS techniques for decades. One other big advantage is you use less energy, less exaggerated movements, and less wear and tear on the joints.
The nuances are not easy to detect, there are many differences even at this level. Imagine how precise you have to be when coaching World Cup skiers. This is rather easy for me to break down. If you watch the follower he uses almost no tipping to get his skis to an angle. He is projecting his hip and pushing his skis to the side to achieve one edge angle. If you watch the lead skier he's developing tipping right out of his release into the next angles and building the tipping and angles progressively. If you follow PMTS Direct Parallel teaching you know that tipping should be continuous through the arc, never stopping until the release. That's only one aspect of what is happening which is different between the two skiers. Also because the follower isn't using lower body tipping he has to redirect his skis with a pivot. Notice how his skis don't make contact in the arc until the edge is set. (His ski angle remains the same once it's established it doesn't increase). These actions result from his use of hip extension (projection) early in the arc which you see by the raising and lifting of his outside hip at the top of the turn.
Skier limitations are based on and created largely by the emphasis and descriptions, therefore usage; of steering, rotary, and twisting movements endorsed by traditional ski teaching. Even the commentary for World Cup racing on TV has pressure and rotary description emphasis, that doesn't describe what the World Cup or the best skiers do. These are outcomes and outcomes are much easier to detect (that's why they fall into these descriptions) than what the skier is actually doing. Without lower body tipping movements and angle development, required pressure and direction control are compromised as in this video demonstration. I have yet to hear one TV commentator describe that early angle development creates the pressure the skier uses to hold an edge and turn a ski. It sends the wrong message to continuously talk about developing pressure, as the skier then tries to push the ski edge into the surface, which has never yielded great skiing. This is why in PMTS Direct Parallel and in Harb Ski Systems we teach movements that create ski angle development and all of the mechanics that support it. We left traditional ski teaching behind and developed our own system because I saw how futile the rotary, steering twisting emphasis was to develop into an expert skier.
