OK so far. > > ... Yes this is the public face. Everything you said was in the article in BSAC Diver. I found it quite amusing because it presented a fairly balanced argument and then right at the end they said (paraphrase) "We don't endorse it", followed by the comment you made: > Their attitude was that 'this isn't for club dives - if you want to do it, > do it on your own'. > > I think Alan's read a bit too much into the tables I thought much as you did until one of the BSAC people in-the-know joined a buddy of mine on a dive (following Greg Dawe's suggestion perhaps I should not name him). He revealed that there have been very heated arguments at committee level and that the real central reason for not endorsing nitrox is the tables. There are no real technical arguments against it and certain inner-sanctom members would like to endorse it. > - sure, they've put a lot > into the 88s, but couldn't they re-run the model for Nitrox mixes and > produce a few more expensive books to sell us members? I don't know much about the 88 tables (only what's in Lippman's book) but I understand that it would be a problem. I am happy to be corrected. Alan awright@gs*.bt*.co*.uk*
