Subject: Re: Origin of Deep Air Thinking (Was: Learn from the mistakes)
I did not misunderstand Ingemar - what I do not understand is why there
are idiots out there teaching this kind of thing. I have seen no
software that accounts for the real shape of decompression, but then
ther is no one model that does it. You have to combine moddels, and some
of them do not lend themselves to computer interpretation. For
simplicity , I would run a Bulhman with zero "safety" factors and
combine that result with deeper stops without telling the model you are
doing that. Check the deep stops separately using the model to see how
much they are moving your ceiling, and reset for different guesses until
you see the pattern working properly - at least that is close to
reality. We have always had to "trick" the deco programs to get anything
that approaches what we already know works.

  This will not hurt you , and it will work a lot better than the model
itself. You will basicly end up with a relatively short, but multi-stop
deco.
