rotary - as the edges are being changed and flat you aggressively pivot the skis towards the fall line. The pivot point is much forward of your boot. The steering should be happening after the edge change if it should happen at all. Well at least while it can and IMO every single turn in this video can be edge to edge. So [edge change(guiding)edge change] instead of [edge(guiding) change]. The steering motion is coming from the femur joint in this phase as well as all phases this is a good start. the turn can be possible more shaped but I am not there so I do not know.
Edging - the skis are pivoted and then the edge change finally occurs, this make it impossible to get on high edge early in the turn or for much shaping to occur. You also on late you edge most on the bottom of the turn, which again makes it hard to be on high edge angle early in the turn. again TIP then Steer not TSteerIP. the edge angle here are being created by femur rotation, which is good.
Pressure Control/balance - your move laterally into the turn following your large edge set upon finishing with large edge set at the bottom of the turn. The large extention move that accompanied the move to get of your edges at finish again make its nearly impossible to shape the top part of the turn, The ski are too light to be shaping at all, and you balance is mostly on your inside skis. This is why I think white pass turns should be the last things you should be doing. You pole usage is much to inside here and causing you to move laterally instead of forward. In the bumps your pole usage is again lateral and your to early. You balance seems to to be slight to aft here leading to the forward pivot of the ski. Your shin and back angle look matching here but I think your knees are overly flex.
rotary - as you come into the fall line the skis continued to be rotating from the tips instead of the from center. This is leading to again very little shaping being done at this stage of the turn. As the heels are pushed out trying to find something to grip. Aft balance here is leading to some hip twisting, with some steering motion coming from the upper body.
Edging - the skis are continued to be pushed as they still have not found anything to grip. The edge angle could be much higher here if the edge angles were lower though the finishing phase. You lefts turn on the groomers are significantly less heel pushy than any of your turns on off piste/bumps. You start to use some hip angles here instead of just upper leg angle to create your edge angles.
Pressure Control/ balance - your are just starting to find your outside ski here but its happening too late in the turn. there are instances though where your lateral movement takes you totally off your outside ski even though this phase. as your COM is finding your BOS(base of support) your balance is now getting to far forward which is helping to facilitating your heel pushing. You are starting to down weight here in order to catch yourself for the up coming edge set. Your inside half falls behind here as you pivot and tip you hips.
rotary - you have forward pivot point yourself to an edge! Good news this is closest you get to turning your ski from the center. You have also lost most of your counter that you started to lose during the shaping phase.
edging - your found them! there they are. This is the edge angle we should have found in the shaping phase. The late edge set builds a ton of pressure and makes it very hard to start your next turn strong. You hip has dipped very far into the turn at the point causing you chuck them laterally into the next turn.
Pressure Control/balance - you have found your outside ski! Again it happened to late though. Your what appears to be centered on your skis although your balance is starting to move aft at the very end of the finishing and its to far inside at this point in the turn. This is almost foot squirt but not quite... You also have lost most of your counter/angulation and IMO in short turns more is better. I like very square to fall line in all phases of the turn for short turns.
stay turned for the what I think should happen.... in prescription.
