Incidentally, on the subject of plots, if the user dives with the handsets switched off on the surface, breathing on the loop 30 seconds before they dive, they die after being in the water just 10 seconds, and the profile goes straight down. If they have a short swim to the shot, then failing to switch on the handsets will kill the diver even before the dive begins.
If this is the case why can most people hold their breath (if forced) for 2mins? I think you are confusing hypoxia with death and it all sounds a bit dramatic to me - don't get me wrong I understand the importance of your message.
Furthermore, I wonder how these figures are calculated -since the last time I dived CCR (admitidly a year ago) I don't remember the PO2 falling 0.05 in 30 seconds.
