....Many stumble on the IP which seems a little odd given it is the lowest performance task. Guess there's too much time so the brain gets over- involved.
My guess is that CSIA's intermediate parallel turn is like PSIA's basic parallel or open parallel turn in PSIA. I don't think it's always simply over-thinking or self-consciousness that causes candidates to mess this one up.
When I first took my LII skiing exam in PSIA, my basic parallel turns suffered from the first two of these technical issues. By the time I took it the second time, these issues were gone.
First, it's important to recognize that these are deliberately skidded turns which should enable the instructor to ski in front of the student, at the radius the student is being coached to make, and at the student's pace. The instructor should not speed ahead, but stay barely ahead of the slow and careful student, demonstrating good fundamentals.
--Often candidates are not able to slow themselves down enough.
--The candidate may push the tails around at initiation with the pivot point in front of the boot, effectively pushing the ski to an edge at or just beyond the fall line.
--Or the initiation may be a rotary push-off, which lacks a functional release.
--The candidate may be aft, or following the skis, or using upper body rotation to initiate the turn.
--There may be a wedge entry to the turn, a sequential entry, or an A-frame signifying unequal edge angles.
