I know you or I don't either Thal, but there seems to be some disparity between what the organizations feel is required to produce a safe diver and what many Instructors feel is necessary! Why is this?
Well I guess it's
a) partly because instructors are divers and curriculum builders are academics. One discipline takes place in an alien environment in which human beings cannot survive without life support and you're down there with people who have children, wives, husbands, mothers and fathers and who sometimes need your help to stay alive and the other discipline takes place in board rooms and behind a desk with "teaching aids" like white board markers and coffee cups made of environmentally friendly styrofoam.
b) partly because few, if any, curriculum builders have ever seen a dead body with frothing pink foam coming out of it's mouth.
