Sorry for the long delay - some people have a life...
Bolter asked for an MA based on steering skills. I'm doing this MA based on rotary movements as defined by PSIA. I posted the visual cues for rotary movements earlier. This MA will review the video clips with respect to each cue.-The skiers legs turn underneath a strong/stable torso to help guide the skis through the turn.
We can see your skis pointed more to the sides of the trail than your chest, thus your legs are turning underneath your torso. Your torso does move both vertically and laterally, but they are definitely not initiating the turning of the skis. Relative to the amount of guiding from leg turning (as opposed to the amount of leg turning from following the skis) the torso movement is small enough to keep the description of the torso as "strong/stable".- Both skis and legs turn together throughout a parallel turn with the femur turning in the hip sockets (instead of the entire hip coming around).
We can see the hips turning to point slightly to each side of the fall line, but the skis and legs are turning together and separately from the hips.- The skis are tipped and turned an appropriate amount to create a smooth C-shaped arc.
In the first clip I see a slightly pinched "c" shape versus a rounded "c" shape, but this is still a smooth "c". In these turns 98% of the turns are coming from tipping. The slight amount of guiding of the skis is appropriate for maintaining a smooth turn (I'll address this in more detail later). In the other clips I see less of a pinched shape, but still a tendency to "crank" the turn in the fall line.- Rotary (steering) movements which redirect the ski at turn initiation are matched in timing and intensity by tipping the skis to prepare for increased forces caused by edge engagement.
There are no steering movements to redirect the ski at turn initiation.-Rotary movements should be progressive, except for athletic moves needed to recover balance.
The movements are overall quite progressive. However, there is a tiny rotary movement "dead spot" at transition. This can be seen at the end of the first clip by the straightness of the line in between turns. On the right turns, there is a small up move occurring in this dead spot.
Here is a still from the first clip at 4 seconds showing a position just before the right turn is initiated.
Right after the position, the up move is the easiest to see. You can't see the right ski tip, but it appears that the right toe is behind the left heel. The further the feet are apart, the harder it is going to be for the new inside leg to tip into the next turn. As you rise up, you bring your feet closer together. Only then can you start tipping into the new turn. But this happens later than your left turns and the result is the next position from the middle of your right turn.
Here the skis are diverging and the outside ski is beginning to fall behind. You correct this nicely by tipping the outside foot. In most turns, this causes the outside ski to engage more and then rejoin the path of the inside ski. In some turns, there is a tiny amount of pivoting at the foot to assist this correction. Sitting in my office chair, if I tip my right leg by moving my knee and don't allow my foot to slip on the floor, then the chair turns. If I allow my foot to slip on the floor, I can tip my foot without moving the chair. In this case, my foot pivots on the floor as I tip. It's easiest to just pivot the heel out, but it's possible to pivot from the center of the foot. I believe this is the "tail washing" that others have observed.
Ideally, we want to check our carving by viewing pencil thin tracks on groomed snow. Because the snow is not packed corduroy, it's hard to use the ski tracks to prove skidding/tail washing and even more interesting that I'm going to use the left turn to prove it.
Look at the left turn track in the pic above. You can clearly see where the ski track marks are wider in the belly of the turn (compare to the right turns) proving that some skidding has occurred. This is an example of guiding the skis/steering the skis. It's good skiing because it's an example of an appropriate amount of turning to complement tipping in order to achieve a "C" shaped turn.
Now here's the same pic with straight lines drawn from the apex of one turn to the next.
Ideally, for round turns, we'd expect to see more deviation of the tracks from the straight line. It's my contention that these tracks are a visual representation of the "dead spot" that I referred to above.
My rotary based suggestion to cure the dead spot is fix the discrepancy between the angle of the line between the toes (tip lead) and the angle of the shoulders (otherwise known as counter). Either you can finish your turns with more turning of the legs relative to the shoulders to create more counter (and let your new inside foot catch up earlier) or you can incorporate more forward movement in your turn initiation so that you more aggressive guide the outside ski through tipping movements earlier in the turn. The idea here is that we want to change the timing of the appropriate tipping and turning to unpinch the "c" shape. This will eliminate the slight steering/ski redirection in the belly of the turn that some have observed as tail wash and reduce the amount of torso movement.
Now I have a question for you. This is how I would try to ski if I were running gates. If you put a gate inside the left turn in the last pic, is that the line you would want or would you have preferred a different shape?
