Just checked the exact requirements in the PADI instructor manual.
"Breathe effectively from a free-flowing regulator for not less than thirty seconds"
and the description includes the sentence
"Stress that students should not seal their mouths around the mouthpiece"
So no sipping required.
I'm far from being an instructor, so maybe I'm missing something here, but .... that does almost sound like it should be "sipping" to me. I mean, if you are holding the reg in your mouth normally, aren't your lips more-or-less "sealed" around the mouthpiece? Or close to it?
What IS the reason for the "sippy cup" method, presuming there is one (that is the way I learned, btw). I haven't tried it but it seems like holding the reg in your mouth normally might be a bit "violent"? :shrug:
