So the people in the video more than likely attain L2 before the bar was raised. The reason it was raised was because the gap between 2 and 3, as evident in the video, was too wide. If you look at the L3 prep at Gore from 2015 (1 year later) you see a higher skill set. Perfect no, but all skiing better than the Jiminy L3 prep (Feb 2014).
Better yes however of those candidates, if in an exam, I would still grade almost all of them below the L3 bar. You can take this with a grain of salt, I am not an examiner..
Like in the Jiminy video, there are still a lot of alignment issues and balance in motion problems. especially in the slower balance oriented tasks. (1 leg skiing for instance)
I"m not saying you can't achieve very high levels of skiing with poor alignment but it's harder to do so. Combine that with the goal of presenting a real good visual image to your students, and it's nearly impossible. I know there are some great boot alignment people on the east coast and I seem to recall hearing that some clinics were offered at some of the division events. Why would someone who is thinking about going for their L3, not take advantage of this and really supercharge their understanding of biomechanics at the same time. Just sayin
