Raven 8-12 seconds of useful consciousness is the same for any one at the pointy end so purely saying having a very experienced captain does not make him less susceptible to hypoxia. Likewise 99.9% of pilots have never and will never experience a real depressurisation so you cannot definitely say how anyone will react, all we can do is train.
Slamming in to a CB? it is not too difficult to dodge some CBs in the cruise but it does sometimes happen. Look at the recent 330 incident with the windshield break, were both the guys up the front cadets with 200hrs?
Your comments have nothing backing them up, things can and do happen in aviation but we train for it. Airlines have been doing it for years, are QF SQ and budget airlines all over the world having major issues?
