I guess I must have been very fortunate to have some real gents as instructors (or they have been scared dumb
).
When being checked out on an unfamiliar a/c,I have received a ground briefing (which is always a 2 way affair,not a 'lecture').When performing an action,I have always spoken what I am doing/speeds etc to let the FI know of my intentions.They are usually happy to accept 'my' way but I am pleased to accept comments like 'maybe you're a little high' etc along the way.Never had any real issues,the debrief seems to be the best place to discuss the finer points and I think you absorb it better when back on the ground.
Keep talking to your FI's,mine have always been happy to respond to emails regarding flying techniques.
