What bugs me with the hypoxia hypothesis, is that the first actions are to put your masks on and establish comms, and only then do you start the descent...
You want to stay concious so it makes perfect sense to get on O2 ASAP.You then need to know if you're carrying out just the PM actions or just the PF actions. So you check the other guy is ok, then down you go performing your own actions. If the other guy ain't communicating then you're on your own and must do both the PM and PF actions.
