Gary,
My comments above were just meant to clarify the standards and my own position with regard to children and deep diving. You and your daughter seem to have come to terms with your own way of doing things, and that's just fine. I only worry about standards violations when my own students are involved or when I see instructors grossly violating standards. Two feet of depth wouldn't be enough for me to worry about with a deep dive. I might question the instructor's judgement, but then again, I am very conservative when it comes to children and diving. As for peer-reviewed, blinded studies, I think we'll have to wait for a long, long time for those...
***************
On the other subject (vomiting through a reg), all I can say is that I've vomited underwater a few times and I've always moved the reg to one side of my mouth and vomited into the water, not the reg. I know that many people disagree, and I teach PADI's position of vomiting through the reg, but I have had great success vomiting to one side, swishing with seawater, and then getting my next breath through that clean regulator.
As for the issue of dragging the octo through the sand, I agree with you, Gary. That's why I donate my primary regulator and then breathe through my octo, which I keep on a bungee necklace. If you're interested in learning more about that technique, just do a search on Global Underwater Explorers (GUE) or Doing It Right (DIR). You'll find plenty of info and lots of discussion...
Safe ascents,
Grier
