AnFi,
Having read all this, as far as I can see your theory is based on your own subjective assessment that 20-30% of people can't process visual references normally and therefore need showing techniques that they should use to guard these references whereas the rest of us learn through experience how to do this (helped or hindered by the 5 hours basic IF)
My problem with this is the only source for this info is you and who knows if you are right or not, you sound like a doctor defining a new illness with no peer reviewed evidence to back it up.
I just don't buy the idea that 20-30% of pilots out there have got their brains wired differently, I think we just have many people of different abilities and that the current IF training is not vigorous or relevant enough and suggests to the student that a 180 turn is all you need, and that cloud avoidance is undertaught as a skill. That's it really.
