I was doing my best to let you off the hook, and concentrate on our
AGREEMENTS that the correcting calibration can ONLY be done in water,
but you chose to keep harping on your ROUGH estimate you had already
withdrawn as the first approximation.

I think it's counterproductive to carry on this conversation.

Let's let the READERS re-read the thread.

If was necessary, to point out how certain INSTRUCTORS are erroneous
and completely off base on the matter of weight calibration. So,
your style is to sweep such under the rug?

Then I have to take back what I said about your understanding of
weight calibration, because if you don't understand Archimede's
Principle and how it relates to buoyancy, then you're back to your
fantasy of the floating bucket.

I gave you the credit you didn't deserve, in retrospect.

You have now revealed that you didn't really mean what you said
about fine-tuning. Else why do you keep harping back on your ROUGH
estimate which was inappropriate and NOT used by you.

Smiley notwithstanding ... YES, about YOUR pointless rehash.

I would have agreed then. Not now. But I don't see any point in
going any further. If you couldn't accept an intended compliment
and statement of mutual agreement, and have to come back to CANCEL
the source of the compliment, it's best to leave it as is.

There are plenty you can find in the archives of what I had said
BEFORE 1994 about buoyancy and weight calibration -- no different from
what I said today. They are the PRINCIPLES that debunk what
Instructors
and many divers did a decade ago, and many of them continue to do so.

So you had almost 700 dives, mostly in cold water. I've had that many
dives, in cold AND in warm water, a decade ago, and quadrupled it
since,
and observed THOUSANDS more divers than you did today, even back in the

early 1990s.

Your wishes granted. 15 points of demerit, for your effort this round.
