Per my earlier post,
https://telemarktalk.com/viewtopic.php? ... 928#p60554 , the "observation" is faulty and phase-shifted by 90-degrees (think sine wave).
I think where the mix up is happening is the difference between "sensing" (feel, sight) versus "indicated" (measured, etc.).
Sense -- one looks at the GIF or video and tries to "catch" when the skis are even (versus staggered).
Indicated -- as staggered is a lower stance and even is a higher, one looks for when the skier's head is highest "indicating" the skis are even.
Let's look at LoFi's first GIF...
I think it's clear the skier's head is the highest (thus skis even) when crossing the fall line, not when skis are farthest from it.
Let's look at LoFi's second GIF...
The pattern is narrower, tighter, and at the first "even" orange mark the skier's skis also appear to be, but not at the second -- INCONSISTENT.
Now look for skier HEAD HEIGHT, again it's highest when crossing the fall line, not at the sides.
Last let's look at the SKI TRACK, and where it is narrow (skis even) and wide (making a turn). It's narrow where the first pair of even orange lines are, and wide at the second.
How do we explain the skis looking "even" mid-arc at the first instance in the second? Simple, the skier is SKIING AROUND THE CAMERA(MAN) thus the apex of the turn (as well as the transition between turns) is not the same as the following turns that are "in rhythm." The skier comes in from the far LEFT side of the frame, then proceeds down the MIDDLE of the frame -- that first turn in non-representative of the latter ones, but it's "pattern" is nonetheless (falsely) superimposed on them.
Alternative proof, and lifting from my
original post on this, let's look at it not as Left and Right turns, but as ClockWise and Counter-ClockWise (Anti-CW for Brit's).

I'm confused about when the lead change happens.
I've been looking at this awesome resource
https://www.qgdigitalpublishing.com/pub ... &ver=html5
In the diagram I screen shotted from the ^ resource, I drew an arrow where you've finished the turn, are traversing a bit to the right, and then MAGICALLY have turned to the left to be in the fall line.
HOW DO YOU GET THAT WAY IF YOU'VE BEEN TURNING RIGHT?
Per the above "understanding" with the switch (from CW to CCW, or vice versa) happening at the sides yields this... one arc made with different entry- and exit- stances. (Paradox)
Blue is (turning one way),
Red is the switch,
Green is (turning the 'other' way).

By contrast (and per my OP)
Blue is (turning one way),
Red is the switch,
Green is (turning the 'other' way).
Stance is consistent with arc.

Lastly, let's revisit the OP's diagram which hides another paradox:
The "offset" goes from 0 to 1 to 2 to 3 to 0 to -3 to -2 to -1... in terms of offset.
Which of these two Versions best depicts a skier making turns.
Which of these two Versions best depicts a the orange ski-position lines drawn in by the OP and LoFi.

The one matching the Orange Ski-Position is NOT a smooth flowing ski path like a Sine wave akin to a ski track left, rather it forms kind of a Syncopating Step wave. NOTE the transition from blue to green, versus green to blue.
Still not convinced the OP's depiction (and LoFi's) is wrong, note how one turn comes out of the "switch" with Slight offset in one direction, but MAX offset in the other direction. The asymmetry, again, "indicates" the diagram to be wrong.
