MikeFerrara:You have to wonder don't you?
I taught more than a few PADI rescue classes and I don't even remember a BB ascent being part of the class. I'm ok with rescue students being expected to do it but not when it isn't taught in prior classes, not to mention the way that buoyancy control and ascents are taught.
And then the "excersize" falls apart and divers can't hardly find and clear their own regs?
What ever. LOL
I don't recall doing BB in my PADI Rescue either. And like you said, not having even done it before, well it would not have been wise to incorporate it into that class. There was enough going on. I was introduced to it in my DM class. We had to BB while exchanging full kit on the bottom of the pool. I must admit that was stressful and rose up some anxiety for me. It's tough enough to swap out gear underwater, but add to it no mask and a buddy that is starting to "hog" the reg, the pressure to succeed (performance anxiety) etc. etc. you can see how that can go. But that's what the exercise was designed for. To push you underwater to see how comfortable, or uncomfortable, you are. And it really enforces that you have to solve problems underwater. And it was done in about as safe an environment you could train in while under direct supervision of the Instructor.
