Well, its a bit late to find out that you've got gas for 3 minutes for both of you after your buddy has ran out and youre 4 minutes from the surface?
Not really.... You now know that you will run out before surfacing, And can... A: try and slow breathing rate... B: have the better diver do a OOA free assent as you near 50-60 feet... WORK THE PROBLEM.... And also why I love hanging a deco bottle at 20' from the boat... You just got to make the bottle and then make up any deco time....
