Subject: SHAPE of deco curve
Art - the shape of the curve looks like any decay curve in nature. It
is most easily described using Fibonacci numbers if the right gasses are
used, only you "SHIFT" the sequence for the bottom time and depth to the
left to eliminate the unneccary excess shallow time ( since we know that
maxes out with time, and you shorten the numbers where the gas is lean
and lengthen them where rich ( the opposite of Bulhmann).

  A better shape would look like a parabola but again, you lose the
"infinity" end.

  You can look at the shape created by any deco program to see the
general patten, and apply that across most dives and then clean it up.
If you look at enough scenarios, you will get an image that you can
carry with you in most situations.
