Yes, I do believe something along those lines should be required for a normal recreational diver. I have no apologies for my position--it's mine and I stand behind it. Just about anyone should be able to do a circuit swim like I described with a little bit of pacing and stamina.OHGoDive:Ok, strenous, no doubt. But, in all seriousness, you don't really think this should be required for the generic recreational diver, do you?
Not all of it is about being comfortable in the water and seeing how long you can swim--part of it is about teaching someone to pace themselves and to slow down when things get rough. See my sig line for more details.

As an example, you can usually tell with decent accuracy who's going to finish first on the 450-yard swim within the first lap or so. If the time limit is 10 minutes, then you should average (max) ~1:06 per lap, preferably ~1min/lap just to stay on the safe side. Unless someone is a competitive swimmer, if they start off at 30 seconds/lap they'll generally end up at 2+minutes per lap towards the end and they'll be lucky to finish. The person who paces themselves at the beginning is the eventual winner (not that it's a race) and won't be as exhausted. People need to learn to slow down on scuba...
