John, you pegged the point for the whole thread in the first place. I haven't participated in a lot of classes (1 OW class, to be exact) and only witnessed a few more at the local quarry. I don't see the whole "overwhelmed OW diver" thing that I see mentioned on SB all the time. This thread was specifically because it seems like fear mongering to me and it's incredibly annoying.In other words, I don't understand the thread. I don't see students overwhelmed by the OW materials at all. I see them learning it easily and confidently. Oh, I do see exceptions, but they are usually students with some kind of a mental block related to the learning or testing.
I recognize that a lot of us newbs think we're better at this than we actually are but doing this sport safely simply isn't that difficult. It takes a modicum of thought and consideration for the "what if" scenarios but it's not brain surgery or nuclear weapons design. It's simple gas laws (that are often blown far more out of proportion than necessary, in my opinion) that can be demonstrated to a child in a matter of minutes, and then practice of a few basic skills.
I just wonder why so many people seem to think that it's impossible to learn all this stuff in a short period of time. Master it, sure, I get that takes practice but saying it can't be learned in a few short sessions or that it's overwhelming to most people seems a bit of a stretch.
