You're missing an important distinction between what you're trying to say, and what I said. I said the training PROGRAM was poorly designed. You're saying the course, including you, the instructor, their work, AND the program itself ALL combined was effective at giving you skills or improving your skills. Those are two completely different things.
As I understand it (and I could have heard wrong, but either way it's a good illustration of my point here), PADI's original self-reliant course was effectively "here's an outline, instructor go teach them to be self-reliant". That's a terribly designed course. It doesn't mean that between the student, the instructor, the terribly designed course, and whatever else they may have utilized that the training couldn't be very effective. A badly designed course does not have to equate to "completely ineffective training". I can take a terribly designed car (missing basic safety features like ABS and airbags, with or without shocks, etc for instance) and use it to teach someone to become an excellent driver - that doesn't mean the car was well-designed, it means the training as a whole was effective in-spite of the poor design of the car (not a perfect analogy, but good enough I think). Similarly, a decent or good instructor can take a poorly designed course and often do wonders with it. Do you see the distinction between the quality of the training (as a whole) and the quality of the program's design?
Either way, I won't be taking the course with GUE anyway, and my professional opinion (or maybe anyone else's opinion) about their course design isn't something I expect anyone else to do anything about.
