It never ceases to amaze me how people will trust a $49.95 piece of software
written by a guy they have never met before they will trust somebody they
are standing there talking to who does this stuff on a regular basis.

Hey, Mike, where do you think Abdur gets most of his ideas?  From input from
the WKPP, Richard Pyle and others out there doing the dives!  Why do you
think we are not on version 1.0.  Because this stuff is evolving.  The hard
data IS our pesonal experience.  We are the guinea pigs.  There is no
controled scientific data because nobody is stupid enough to do this kind of
diving in a lab.

I am reminded of a story Joe Odom told me.  Chris Parrot, after launching
his very successful decompression software program, the Abyss, decided he
probably should learn how to trimix dive.  Chris met up with Joe at 40
fathom shithole, Joe described they layout and asked Chris what Abyss said
the deco should be.  Chris supposedly whipped out some tables and
confidently gave them to Joe.  Joe looked at them and put them in his
pocket.  "What next?" asked Chris.  "Get your shit and get in the water,"
Joe replied.  "Uh, what a minute, I need to check something..." Chris
supposedly said.  "Nope," replied Joe, "nobody else get's to 'check
something' when they use your program.  Get in the water and let's see if it
works."

I love that story.
