I basically agree, Richard, however, I was a CFI with real world experience, and the industry didn't like being taught how to fly after they'd already qualified for a license and instructor rating, especially those with lots of experience.
I once had to train Qantas Flight Engineers who were being retrained as pilots after the 747 Classic was retired, and one old chap really didn't like the idea of throwing an aircraft around the sky in a Decathlon. The only reason he did do it was because he had to, Qantas were paying, and I wouldn't accept his refusal, despite him being older and more experienced than I.
It ended well though. Once we'd finished, he'd appreciated the training and thanked me for it.
