Mature, MarcK.
It's interesting that you think you know what height I stall at. I simply offered my personal thoughts based on my own experience. If you choose to speak to your students in the same way as you just responded to me, I feel sorry for them.
I have found the comments regarding managing displacement in strong winds during stalling to be valid. The first time I stalled a C172, a long time ago, we were actually moving backwards, with a negative value for the ground speed.
