I'll be the first to admit that I don't follow this sort of thing, but my initial reaction is WHO CARES?

Its a gimmick using 100% 02. If we aren't going to use natural air, why pick 100% 02? We could also keep records for 25% 02, 50% 02, 75% 02, etc. Then if someone breaks your record for, say, 50%, you could always just change to 48% or 52% to set a new record.

I'm reminded of Pipin when he set a new record for depth using just one breath from a scuba tank and justified it by saying that the event was "no limits." How many breaths does it take before its scuba diving?
