Theres around 60 Keys, but don't let that bother you.

>I forgot to mention that harebrain fussed at me because I got on
the boat about 1 minute late -- because I was timing the dive
according to my COMPUTER, which stops the clock above 7 fsw,
the times I pooped to the surface, from 30 fsw, in SLOW,
CONTROLLED ascent of course!   That accounted for at least 1
minute of the time that DM forgot.  ;-)<

The DM didn't forget the time.  You did.  If your COMPUTER doesn't continue
to count time above 7 feet, you can hardly claim to have been using it to
tell the duration of your dive while you were there, could you.  Guess what,
it's your job to keep track of the your dive.  Personally, I suspect there's
more to the story.  I've never had a DM, anywhere, fuss at me for one minute
over.  If you did, I agree it was over the top, but it was still your
mistake.
