Not sure I agree about a limited amount of instrument training however, it may lead to people putting themselves in situations that they haven't got the skills to deal with, but think they might since they did a few hours of instrument work. If you want to do instrument training, do the full IMC course. I'm not particlarily happy about the instrument training involved in the PPL as is.
Maybe i'd settle for Ex.19 being taught correctly but the first few hours of my IMC made me realize how inadiquate my instrument flying was - and how easily inadvertent IMC could get me in trouble. A level 180 on instruments is all very well, but IMHO the skills leading up to unusual attitude recovery on instruments should be taught. And practiced!
That's what i'm getting at.
I guess "people putting themselves in situations that they haven't got the skills to deal with" could easily apply to the IMC rating as well
