The reason Andrew does this drill, is that people around here typically cheat and instead of having proper undergarments they have a ton of gas in the suit. The drills are usually done in 20 feet of water, and the sqeeze isn't all that bad. Andrew is trying to get you used to divign the suit squeezed, and not like a big balloon. I agree that it's a bit extreme, but it also shows you how much excess lead you are carrying. I was wearing a 16# weight belt, now I'm wearing none!
