I didnt catch that.Also not trying to sound snarky... if he's at 80 feet and he has significant nitrogen loading from two previous dives that day, and he's advised to make a five minute safety stop because of that depth and that many dives... gas planning probably won't be much of an issue because that third dive will be limited by his NDL and not by his gas supply. In other words, he'll have plenty of gas for whatever happens.
If I was in the scenario you described, I know I'd still have more than half a tank when it was time to end the dive.
This is why I like these discussions. Good observations and thought gaming comes up and allows for critical learning
