Back to your question.........
Excellent, we're learning things that we would not learn in flight schools!
I do have a slight appreciation for the high altitude approach to low speed concern, though the highest I have ever flown was 25,000 feet in the Piper Cheyenne, but we sure didn't stall it up there! I also appreciate that some types (including the Cheyenne) have stall barriers to meet certification. That's fine, that's a part of certification, limitations, and type training. All the more reason for instructors to remind themselves that there is lots more to be learned outside the flying school!
