The basic decompression algorithm used for the computer is
Bühlmann ZHL-16C. It has been modified by the use of Gradient
Factors that were developed by Erik Baker. We have used his ideas
to create our own code to implement it. We would like to give credit
to Erik for his work in education about decompression algorithms,
but he is in no way responsible for the code we have written.
The computer implements Gradient Factors by using levels of
conservatism. The levels of conservatism are pairs of number like
30/70. For a more detailed explanation of their meaning, please
refer to Erik Baker’s excellent articles:
Clearing Up The Confusion
About “Deep Stops”
and
Understanding M-values .
The articles
are readily available on the web. You might also want to search for
“Gradient Factors” on the web.
The default of the system is 30/70. The system provides several
settings that are more aggressive than the default.
Don’t use the system until you understand how it works .
