I don't know that I would have changed anything. I took the NAUI program in '88 and it was EXPECTED that a new diver would take OW I, OW II, Advanced OW and Rescue in quick succession. So this was the program and it was spread out over about 3 months.
The Rescue component was much more involved that the current offering from PADI (I don't know anything about the current NAUI offering). Among other things I had to write a paper on common diving injuries and state the appropriate first aid for each. This included, of course, injuries from marine life. This paper was the better part of a dozen typed pages.
Since all training is local, we didn't talk about the problems of wetsuit compression, huge amounts of ballast and the complications of venting air during ascent. We sure didn't talk about run-away ascents. I had to learn that when I got back to Calif.
Still, I think highly of the program and the instructor.
