I don’t know about your level 3 exam, but in RM wedge turns are a task that may be examined. The point is a wedge turn can be performed with edge, pressure, and rotational control that accesses ski performance, but that’s not intermediatie technique, it’s expert technique.I don't know, years ago skiing with Bob Peters at Alta he stopped to help a woman wedge turning in a foot of cut up powder on an advanced trail. No huge fat skis as this was 2003. How she got there was beyond me as it was near the end and was no simple matter. It was def not intermediate terrain but not real steep.
At Big Sky in 2009 there were people wedge turning on fat skis in pow down one of the less steep Headwater chutes at Moonlight Basin. Still near 40deg.
Since Mikaela's zipper bump skills are questionable, like Bode's, they are merely advanced level skiers. Not expert. ....
Yesterday we skied terrain that required falling leaf and pivot slips through an entrance to a couloir that was 50degrees and about 190cm wide — I was on a pair of 180s. I don’t think intermediate technique would’ve made it. And the consequence of a fall was pretty high — 1500 vertical feet of slope with rock bands and cliffs all over 40 degrees.
