I was a rebreather diver for 8 years (I sold my last rebreather this year). I always had a BOV on my loop. Whenever I felt there was some doubt, I would go over to bailout gas and then figure it out. I know some agencies/rebreathers teach stay on the loop until you know you need to go off of it and some go onto bailout for what they call a "sanity breaths." I don't think there is any agreement on this point, and I am not sure my procedure was the best, but it was the one I was comfortable with. For mixed OC and CC dive teams you need to have the larger of enough gas for yourself to bail out on, and for you OC team member to go to in the event of lost gas. For me that was typically, what does the OC buddy need for deco in the event of lost gas?
