I'm not a RB diver, so my question comes from a "curious but ignorant" perspective.
Yesterday on a charter, a 2 man team of RB divers stayed an additional 30 mins of deco beyond their plan. We were all on the boat looking down at them. When they were on their shallow stop, a crew member dived down and checked on them. They signaled back that they were OK but that one of them needed to complete additional deco.
I never heard what the issue was, but both were OK.
The dive was planned to 200', and that was the bottom, so they couldn't have gone beyond their max depth. They began their deco pretty much with the rest of us (after 20 mins), so I seriously doubt they exceeded their bottom time. In fact, I think their bottom time was cut short. I'm not 100% sure, but I think they were on Megs. They never left the loop.
What could cause the additional obligation? PPo2 setting errors? Some kind of PPO2 error, I would think...
Just wondering...
