me too, but I have something different to say. As I worked my way up through various levels of adult group, small group, specialty group and private lessons, I am stretched to think of when we ever went off piste.**The thinking I've run into is to strengthen your skills on piste, and then go work off piste outside of the lesson. It certainly didn't hurt me: we get a fairly amazing assortment of crap and crud snow, and I can ski all condition with the best of them.
**one private bump specific lesson ten years ago.
I am also going to repeat something I said in a different thread. What you think you need, and what a qualified instructor thinks you need may be two different things, and you should approach your lesson with the heart of a student. I mean, sure you can be in the totally wrong lesson, but I am willing to respect the opinion of a professional.

So I'm going to stick my neck out and say that I'm not sure what off-piste means, exactly, and I suspect that people don't necessarily share the same definition.
When I was skiing in the 7 group at Breck, I rarely did anything but groomers and pretty small moguls. I got to a point where I felt bored in the 7s classes, but afraid to take the 8s because I was just sure I would be too slow and too timid etc etc etc. Then finally there was a day when I was in a 7s class and just feeling so unchallenged, and at lunch I saw my husband at lunch, with his 8s class. They seemed nice, and I'd met the instructor before. I asked if I could switch to their class, and swore that I would leave if I were holding them back. Mid-day lesson switches are not exactly approved by the ski school, but in this case it was the right thing for me to do. I found out that, yes, I was working to keep up - but isn't the point of a lesson to be working, not coasting?
So now I ski 8s, and I'm always at the lower end of the skill spectrum, but I'm also always challenged and always learning. My skiing has improved by leaps and bounds.
The 8s and 9s classes, after early season, are often in the upper bowls, unmaintained (but marked) terrain, moguls, trees, etc. But I'll admit that they are not as intensely lesson-oriented as I remember earlier classes - it's more of a mixture of class and guided tour, with the specific mix depending on the instructor.
I've definitely seen people who thought they were way better than they actually were, and will never get better in skills because they are "too good" for the drills. On the other hand, in my experience, while I've seen instructors suggest that students go down a level, I have never seen a 7s instructor suggest that a student move up to 8s.
So on some level I think, if you're not feeling challenged, it can't hurt to move yourself up - if you really absolutely don't belong there, the instructor will move you down, or you'll feel overwhelmed and ask to be moved down. (Where it could hurt to move yourself up is if the very first warm up run is way beyond your skill level and you don't recognize it as such, but that seems unlikely.)
