I'm getting more perplexed. So I have a hypoxic dil available at 3m? I have pure O2 at 60m but I don't push the button. The whole reason for an ADV is to simplify things both in normal diving and in problem situations. If I am shallow and descend a bit my loop is already very rich so a bit of dil isn't going to kill me but if I am already solving one problem I don't need to reach for a button to solve another. In the, thankfully few, times I have had a problem in the water the one thing I didn't have was a spare hand. I can picture the poor guy with a sinking buddy in one hand, the shot line in the other and flat counterlungs.
I think we're just going to have to disagree in which case and ADV probably isn't worth you having as all the advantages I think get won't be available to you if you switch it off. It's hardly worth it just for a hands free descent.
