Lee should have noticed that the QUOTE was what someone in TECHDIVER
said to Lee -- about Lee's claim that he could compensate 6 lb shift
[shift in weight of air in the tank from full to empty] during a dive.
I was not in that conversation at all!

What Lee did in rec.scuba, after he was shown the physics by Hugh
Huntzinger, back himself all the way down from 6 lbs to 2 lbs, while
admitting, as Hugh correctly suggested to him, that he was a bit
heavy at the beginning of a dive, and a bit light at the end, and
as long as he is MOVING, anyone can handle that kind of difference.

But the discussion was about NEUTRAL BUOYANCY -- which means not
positive nor negative while NOT in motion.

Trouble with Lee, among his ignorance in physics, physiology, and
other diving matters, is his poor MEMORY of what was being discussed
and who said what to whom.


Just want to set this record straight that Lee shot his own foot
again.   The quote above about the 6 lb shift was NOT something 
I put in his mouth.   If was in a discussion in TECHDIVER in which
everyone was amazed at how ignorant could be, about physiology and
the physics of buoyancy.
