Sean is correct when he says that the regular Bulhman stuff actually
calls for an ascent rate that equals deep stops - you guys are just not
doing them, so you get wacked, and you must do them on all dives no
matter how long. 

  Look at it this way - a 30 foot per minute ascent rate is a 20 second
stop every ten feet starting at the bottom. Not doing that? You are
bent.

  For the dives I do, the times are so ridiculous that I extend
Bulhman's rate as a factor of the bottom time up to 15 times, so may do
5 minute stops startiong at 80 percent of the profile to kick off my
"deco", which is nothing more than 15 times his ascent rate stop , and
this goes on until I hit his "ceiling" or real deco , which will meld
together just using his program due to the fact that errors in his
calculations, math, and theory differentiate between deco and non deco,
which of course is bullshit. The reason any of his stuff works is that
it so closely approximates any decay function that is implied in the way
these differentials of on and off gasssing work, and it is just
"coincidence" that was given to us to protect us from our own dumb asses
that when you apply the correct oxygen window ( through the uses of
different gasses ), it works. Just coincidence, and that is why just
using a Fibonacci sequence is as good as anything you could pay 50 grand
for from an oil company. 

  Richard Pyle's method is fine as well. I have no idea what it is, but
I like Richie, so whatever he does is ok with me, no matter how stupid
it may sound to the rest of you, but then he does not really dive for
very long at the bottom, and neither do any of you, but both you and
Richard must do the deep stops even then, or get injured. That Pyle is
correct on for sure, and the mechanism is not important - just do it. If
you are commercial, and have a chamber waithing for you , you can
accellerate this proces, take the bend, get in the chamber and go to 60
on oxygen, and treat those bends. That is an alternative to doing it
right, and works especially well on those for whom no deco will work.

  There is no benefit to accelerating deco on short dives, but there is
benefit to not doing too much at the intermediate depths, and there is
benfit to planing the dive so that you can get out of the water without
getting killed if something goes wrong - this is why we always have an
intermediate nitrox ( 50/50 ) in the dive, rather than trying to come up
on something like 32 all the way - it just does not work, and then if
you have to get out, you can not. Plan the dive so that if you have to
blow off the whole oxygen stop, you will be ok.
