pull vs. push

A mixup (PF wants to push and pulls instead) is out of the world.

During my instructing air combat maneuvers in the F4 it never was very difficult to get the students to pull on the stick hard enough, but it was work to prevent him to exceed the allowed g-limit.
On the other hand it was hard work to train the students an effective extension maneuver with close to zero G. At the beginning most just relaxed back stick somewhat and felt unloaded with still 1.5 G on the frame or thaught they had a good unloading maneuver going with 3/4 G.

Same for the duration of the maneuver. Whilst students pulled all the way into the buffet and staying there all day until speed was gone, i never ever had to tell one to terminate his unloading maneuver. Those where most times too short and therefore not effective enough. We taught to unload for 5 seconds, most ended after 2 seconds.

Situation as described above where agrevated by a nose high position, where a hard pull disipated more speed rapidly and the unload had to be way longer until the nose was below the horizon.

It is natural behaviour to pull more and longer than needed and not to push hard and long enough to get a desired unload of the AC, at least in fast flying jets.

How often does an air transport pilot push (not relax) on the SS and feel less than 1 G? And how often in an unplanned situation under stress?
