You are being very silly now.
I asked an open question, because I am genuinely interested in what the forum thinks - maybe not so much in your case, as you are filtering your replies through a pre-expectation.
I repeat that the instructor quoted FAA guidance, so in this context I can pin a nationality on the advice in this context.
There seems to be genuine merit in the instructors argument to me, but like an earlier poster said, it would be good to understand the FAA and CAA views and evaluate the differences in logic.
Also, it would be good to hear from people like Chuck or BEagle who are both very experienced pilots and instructors.
The comment about the Citation is not very interesting to me, since I won't ever fly one of those, but the Seminole is, as I have a little experience of underpowered twins.
The only "jet" experience I have is in a sim and I seem to recall that the recovery on that type (swept wing) was a fairly aggressive push forward at the stick shaker. Mind you, that was an early generation type, with super stall vices and no doubt the technique is type specific.
