Al,

In DecoWeenie, if you are using GF mode (which you should), you don't need
to set conservatism since you could modify that via GF-high value. If you
are really cautious, use the option "Immediate Descent" to gain some
conservatism (amount of conservatism proportional to max depth).

Also, it seems that you are using DecoWeenie version Beta 0.99 which has a
documented bug that the last stop is longer than necessary, so you already
have some "built-in" conservatism... :-)

The latest version of DecoWeenie is 2.1, and the next release will include
Eric Baker's VPM algorithm.

Hello Everyone,
          I have a question for those using deco software. I have been
using Z-planner for the past couple of years. Also I have just recently
tried Deco Weenie.
          With Z-planner I set it to run tables that are 10%
conservative. I know a couple of divers that set there program to 50%
conservative, this seems to be such over kill I can't believe it. They
end up with deco times as long or longer then the times from there TDI
tables.
          We do most of our mix diving in Lake Superior and Lake Wazee
in central Wis. So we are dealing with cold water. Cold being upper 30's
on the bottom and maybe into the 50's during the last couple of stops.
          So finally here is the question, what percentage do you set
your software at? I have gotten to the point that I'm thinking of
setting mine at "0". Even with drysuit, under garment and using argon I
still get cold.
          So fire away, let me know what you think. Is the software
conservative enough or should some percentage be factored in.


Thanks, Al
