Waiting until they run out of gas and embolize is too late. Her buddies had reason for concern. All of this really is a personal risk assessment. Going ten minutes into deco on single tank is fine by me, but clearly it sets off alarm bells for a lot of people, running out of gas is totally unacceptable. Someone with just a few deep dives needs to be very conservative on gas reserves. Do look at the risk of embolism, drowning and DCS and weigh your risk. Where does ascent rate fall in this? Likely off the charts.
700psi is not OUT OF GAS. It is very far from out of gas. SHE decided to ascend at 1100 psi. I highly doubt there's any way to run out of gas on a 6 minutes ascent with that much gas...
Edit: And sorry to OP for those divers that seem to have no respect and/or manners... I can understand that on the tec board, but it's supposed to be flame-free here. I guess it all comes down to the first comment I made on this thread anyway...
