thanks for the useful words.
i have found that simplifying it has helped greatly. flew the lesson with an experienced instructor who gave me useful tips.
by changing the way i talk about the landing and demonstrating it has helped greatly in that the students seem to understand me and respond much quicker and generally tend to do a half decent approach and landing first time... ( they tend to go to pot after!)
the main point of my initial thread was.. do experienced instructors ever " chill " out when teaching this, or are even the old hands permanently on their guard.
