Ken;
If it were so easy to mitigate the evils George associates with elevated PN2, how is it that several recent scientific studies have shown an increase in brain stem lesions and retinal abnormalities amongst sport divers even when they have no history of clinical DCI? Could it be that air isn't a particularly good gas at any depth?
My point is not that George is right or wrong, simply that the long term health issues of diving are complex and no one has found the dividing line between safe and unsafe. Simple rules work best for the simple minded. I guess I give this board more credit than that.
