You're right that it's something of a thread hijack. Nevertheless, here's my response.
...............Contrary to your implication, it doesn't really reflect on these divers' abilities but instead is only a question of statistical likelihood that with so many divers around, some proportion of them will have got bent.
My entire point was that if doctors think Nitrox is good for people who have been bent, it should logically-speaking also be good for those of us who have not suffered from a DCS event, and therefore, when I'm doing a lot of diving, I especially prefer to be on Nitrox.
