The discussion about PSIA Demo Team skiing with PMTS movements, needs demonstration. This is the best skier on the PSIA Demo Team. Two clips from a video, gives us a closer look at this skiing, you can see there is nothing here that a PMTS skier would do, on purpose. I can assure you every turn in this video has these same results. This is an extension or at least a push out, or off the ski, after a late hit, in each turn. I don't call this arcing, because it's not, it's skiing that uses a pivoted relatively flat ski, to an edge set.
In PMTS skiing we develop angles higher in the arc and we in PMTS flex the legs to release. Flexed lags in a transition out of the arc, creates early high angles. Notice how in the back seat the skier is after the push off release. There doesn't allow for a transfer of balance and the skis are not tipped or angled, yet. A PMTS skier would be angled or tipping to the LTE, already putting the new inside ski on edge here.
Reilly's skiing shows the PMTS approach to technique and he is definitely already on edge at this point in his arcs..
In this part of the turn weight is on the inside ski, hips square, knee is driving the angles, but most obvious is the lack of balance. There is little or no balance on or toward, the outside ski.
The whole movement pattern breaks down here at the point where the release should be occurring. A PMTS skier would be flexing to flatten the ski, this skier is pushing on the ski to get more grip so he can extend.
It's obvious here that 2 ski weighting is about to happen again, no inside ski tipping, no pull back, and no counter held from a previous turn.
So why is this happening? There are two ways to approach this skiing. That is if the skier wants to change the way he skis or wants to bring his skiing to a higher level. First, is the boot adjustment and alignment. This skier looks cuff "Over strong" and the signs for this come from the knee drive. Now if the skier in addition to a strong cuff, is trying to drive the knee, it doubles the impact. The other reason for this late hit skiing, comes from a series of movement patterns that the skier maybe trying to accomplish. If the skier is trying to steer the skis with the femurs, or as some call it, rotary leg movements, the ski will come on edge late in the turn. The edge that does result is rarely from body angles and a long outside leg, the angles, usually come from the knee, which is also a vulnerable to place to apply and drive forces.
