个人是非常讨厌做所谓scientific analysis的，在体育领域。但既然扯到这儿了，不妨按那个逻辑走下。
HH用head ski，众所周知。那么请问，head的成年男子ski，无论什么目录型号，最小转弯半径，有低于10米的吗。
高立刃角度，可以缩小转弯半径，也是一个事实。那么再看一遍这个视频：
这里的最高立刃角度，可达到多少？
I say 45度max。小弯，自由滑，这也是高手的最大值了吧。
设想HH当时所用ski最小转弯半径是10米，取最小值；立刃45度，取最大值。按通常的测算标准，可得70%的厂家设定半径，即最小转弯半径7米。
以HH自己的身高为参照，也取最大值，算他身高两米吧，回看视频，他是在转7米半径的弯么？
前面早说过了，他那个转弯半径，根本就是snowblades才能转出来的！
别忘了，HH所谓direct parallel的技术，不要你steering，原理就是现代ski已经内建了self－steering effect，不需要你自转。tipping立刃，让雪板去转就完了。
所以上述完全是按他的逻辑去推演归谬的，并不是俄判定他“事实上”在转腿的依据。俄的依据早说过了，就看他转弯时，雪板运行方向与整体运行方向之间，有否夹角。
有没有，大家自己看就知道。
那么这个夹角是哪来的，如果不转腿，不steering？这位爷难道不是human being当中的一员吗，一般的biomechanic规律应用不到他身上？
其实这也是废话。他转没转腿，看就看出来了，还用得着角度尺＋sherlock啊。
只要你知道转腿是什么。
HH是转腿的，steering的，尤其小弯的时候，早被人讨论过不知多少遍了，根本不是俄的创见。俄哪有那个本事去。以下是引用epicski上某兄的一段话：
I think everybody is distracted by this apparent lack of steering in his teachings - and this is not really an issue here...
I believe the "phantom move" is this gimmick.
Diverging inside ski on a outside edge pushed against FLAT stance ski using boot pressure as a lever provides STEERING.
Paradoxically for this to work well no OTHER steering should be interfering - so Harb is adamant about leaving stance ski alone during "phantom move" - no (OTHER) steering, no (other) edging until it develop itself during the turn.
In all fairness I believe the (first) book do not require boots "glued" through the whole turn (you can see that on his pics) - once carved turn starts with no additional steering required the free ski is coming down to what looks like a natural stance and then during the transition phase the whole "edge/boot steering" thing ("phantom move") starts again...
(Although in a short radius turns where steering is desired for a better part of the turn this "boot" steering is recommended to continue through the turn I believe...)
So steering IS happenning - everybody who tried his method knows that - it just he advocates this particular (if somewhat contrived) way to do that - and the way he teaches it - "phantom move" INSTEAD of steering - confuses the heck out of everybody... "Phantom move" IS the way to steer in his book.
Advantage here is that with his method it is difficult to start skidded turn and it forces the student to quickly develop carved turn through patient entrance and gradually increasing edging. That's what he sells and it works.
But I feel one-legged balance act is a disadvantage in advanced skiing situation...
So, I think it's not an all-encompassing way to ski - but just an instruction technique for quick intro to carved parallel turns...
HH不但转腿，而且转的轻巧，漂亮。甚至隐蔽。因为他有本事在立刃加压之后，仍然转腿收弯。上面那个视频，慢动作，看每个弯过fall line之后的部分，你就知道。
这当然却也不是仅靠观察就行的。在俄来说，有推理的成分。因为这一段如果仅靠雪板side cut自转，不可能转出那么干净利落而圆的弧线来。
作为对比，看他高徒过fall line的部分：
这位高徒的完全不转腿，跳过high c卡low c的大马趴style，别的地方讨论过，不重复。我并且注意到这个坛上的另外一位大侠，通常也被看作是HH信徒的，用exactly the same的方式在滑雪。这其实就是没有high c的zigzag turn，类似于蹭过phase2做一个hockey stop，完成一个弯。
来看一个很有趣的小racer的视频：
注意到每次过transition，小racer是怎么抬内脚，往外脚上靠（其实就是内脚外转），从而触发外脚立刃＋内转，和上身的一个非常自然的向外counter吗。
Looks familiar？
不错，这就是phantom move，而不过是某种宽站姿的，不那么流畅和熟练因而不具备隐蔽性的，U12版本的Phantom move罢了。也因此，我们可以清晰地看到，tipping内脚，是怎样触发外脚立刃，
＋转的。
C党八股立刻跳将起来说，转腿＋edging＝steering。
racer们tipping内脚转外脚，as per Ron大师，是已广泛采用了几十年的技术了：
If, on the other hand, you twist only your outside leg inward and lift your inside foot off the snow, your upper body reacts by turning a bit toward the outside. This sets your upper body into a count-red position, ready for hip angulation early in the turn. This is a technique racers have used for decades. Rainer Schoenfelder executes such a movement in the fourth and fifth frames of figure 4.14 on page 65. Because his right ski is off the snow, the muscular effort that rotates his left leg inward also causes his upper body to turn slightly toward the outside of the turn.

耶经传道书有云：日光之下，并无新事。信否。这里略改动一下，是凡违背common sense的新事，多为无中生有。
当然这里所谓common sense，是局限在牛顿世界里的common sense。若夫爱因斯坦那半拉，俄除了闭嘴，没有别的选择。 |
