Stop thinking about pressure on the controls!!!
Start thinking attitude and picture.
The point you close the power level is really dependent on a few factors wind being the biggest one. Use Q's in you visual reference for when to shut it.
Instructor 1 in your example is one with ideas of grandure flying an airliner.
Instructor 2 is more realistic for a tommy and a GA airfield.
Mind you at 70knts going across the fence it really doesn't matter what you do you have that much energy!!!!
Have a look at your POH and see what speed it tells you to do. 65knts is more normal and personally I do 60 knts over the fence.
I instruct on tommy's and have 750 hours on them.
