While I agree you and it's probably true for most cases it was different for me. I was placed in a higher level group after ski off at Taos ski week than I was comfortable with. I am one of those strange cases when I have good technique because of many lessons, but don't have the mileage to mentally handle some of the more challenging ungroomed terrain/bumps/trees/etc. When the instructor of the group I was placed into initially after ski off started talking about the terrain they wanted to ski I asked to be moved into a lower level group. Then I was placed in a group that was too low in ability because of how I described my skiing ability. Long story short I had to switch groups the next day and I got into a group that was an in between level between the 2 groups they were trying to put me after the ski off and it was perfect! One of my ski friends I was skiing with who is an advanced/expert skier was in the group I was initially assigned to right after ski off and I later found out that this group was skiing off Kachina and lower half of West Ridge on their 2nd and 3rd day of ski week. I was definitely not ready to ski that terrain - I would have survived it probably, but I would not have enjoyed it at all.
I learned to ski as an adult somewhat recently so fear is something I have to work through much more than someone whoe learned to ski as child/teenager. One of the comments I got from my ski week instructor towards the end of the ski week was - "I don't understand how someone with your technique and coordination can't ski more challenging terrain." I need more mileage (or that is what I think) to get there.
I loved Taos ski week and going back for another Taos ski week this year, but the ski off while works for most skiers, is not universal. Although that's true with everything.
