weidelk:All I can say is thank goodness you don't run the ski industry, if you did we'd all be forced to sit through 4 weeks of intensive avalanche survial training before you'd let us on the bunny slopes.
I think you are under the mistaken impression that those of us who advocate a more comprehensive approach to dive instruction think it should be mandatory. I don't and I doubt many others do either. I think a comprehensive approach should be available and I recommend it, but I think you should be able to choose any style of instruction (or no instruction at all) that you like.
Peter Guy:I'm quite sure that ALL agencies have limits on what an instructor may teach in "X" class
There are probably some things I'm not allowed to teach in an SEI class, but without searching the standards, I couldn't tell you what they might be. We have a great deal of freedom as long as we are exceeding standards. I'll try to remember to see what I can find. I do know the limits within which PADI instructors must teach are vastly different from the limits of many other agencies. I do not believe your comparison is valid because it gives the impression the limits are similar. They are not.
By the way, I can and do teach staged decompression diving in my Open Water class. I am not allowed to have my students actually conduct staged decompression dives, but we can simulate them as long as we stay within the no decompression limits.
