Yeah I mean that she is not intentionally creating excessive early pressure (because such is not needed). So she's not pushing or pressing hard, but rather is focused on tipping angles.

 But the fact that there is no change in the direction the skis are pointed means they are moving against the direction they are pointing; they are skidding- liquidfeet.

Skis are moving left she's moving more into the turn. Sure there's a little skidding and pivot. But skis are relatively unpressured as she develops lots of inclination and edge angle by going inside the turn. When they fully hook up they've got lots of edge angle.
No stivot.

I agree. Tina is carving arc-to-arc in that video.

I think you're saying it's not a stivot because a stivot would be a twist of the skis against the direction of travel while they are light, followed by engagement.  

She clearly isn't twisting the skis.

It's just that she's unweighted after releasing and sliding across the surface for a bit before engaging.  Right?

 

Yes. During the float when the skis are not on edge they are obviously not going to turn. The reason she is trawelling to the left in the first 4 frames is that her skis are pointing that way. As soon as they are tipped on edge and hook up they start turning. If she pivotted the skis she would have had to do it when skis were totally flat. And then there would have been snow spraying from the ski in the high-C.

Redirection does not equal skidding.

 

Redirection happens if the skis are not pointing in the same direction as the CoM momentum when they are engaged. This can happen with or without skidding. If the direction difference is large it is virtually impossible to avoid skidding though.

 

On another note. One difference between Tina and Reilly is that she works the fore-aft more, thus enabling an earlier engagement.

Yes, Reilly doesent dropp as far back as Tina at the transition. If you look at both at transition its quite obvious.

 

 

Reily is also showing more counter at the transition while Tina is more square. And Tina starts her turns with inclination while Reily has his shoulder line more levelled.

It's really hard for me to tell exactly what is going on from the photos; I have less MA experience than most folk here.  Still, this is what it looks like to me:

Skis are not turning in the first few frames, as they have been released from their old edges and are not fully on their new edges yet.  The skis are moving tangential direction from where they were released from the old turn.  Tina is moving tangentially from where she was released from the old turn a fraction of a second earlier while the skis were still tipped in the old direction, with a little fudging because she was not fully and instantly released - still some connection to skis via legs.  Tina's movement is a little more down hill than the skis direction, causing her to move across the skis and here legs to tip the skis in the new direction.  When the skis get tipped the edges hook up and turn and then turn her.  Not a stivot.
