The skiers in this video are all good athletes. However they are handicapped by the movements set by the CSIA that they must demonstrate in order to progress through levels 1 to 4. They must extend to release their edges at the start of the next turn leaving only one option and that is to pivot or skid the skis throughout the new arc. They must also complete their turns with their shoulders and hips essentially pointing in the direction of their skis (rotation). This creates several problems for the skier. The tails of the skis skid out at the end of the turn (particularly at higher speeds). The skier can not tip the skis towards their new edges while in this position but rather must must extend to first release the edges. The skier must reverse the momentum created by allowing the body to rotate to this position (shoulders square to the skis) in order to turn the skis the other way. All these problems can be eliminated by using PMTS movements.

At the start the trainer set three goals: (1) round turn shape (2) maintain turn shape to the end of the run and (3) manage pressure. No one, including the trainers, met goals (1) and (3). Why? Because it is impossible to achieve those goals using CSIA movements, namely extension (rather than flexing combined with tipping to the new edges, PMTS movements) to end one turn and start the next. In short radius you cannot create a round turn if you extend to initiate the turn. Extension causes the skis to flatten to the snow rather than tip on to the new edges. Furthermore extension causes the skis to loose contact with the snow. The skier now has only one option, pivot and skid the skis throughout the arc, rather than putting the skis on edge before the apex of the turn and using the shape of the ski to create a round turn. With CSIA movements the skis skid throughout the arc and only at the end of the arc do the skis go on edge causing a big hit or sudden pressure at the end of the turn.

Dan stems or places his new outside ski into a wedge at the commencement of his next turn on most if not all turns. This is not the example he (a level four trainer) should be setting for his level four candidates. PMTS movements would eliminate this wedge by holding the little toe edge of the inside or uphill ski while you commence to tip the outside or downhill ski to its little toe edge.
ps. lelo，我找你幫拍片的地方最少都是紅線以上，還有界外的off區，為何你都拍起來那麼綠呀？我的速度還比他快耶，哈哈。

這是應該是一個 PMTS Harald Harb 的擁戴者
