Hi Paul,

Getting out of the water 3 to 5 minutes earlier is insignificant.  I played=20
with the gradient factors on the program and was able to get out of the wate=
r=20
faster on the DIR deco gasses.  You can get the program to tell you what you=
=20
want if you play with the numbers in the "preferences window."  The trick is=
=20
to learn about decompression theories & your physiology, and follow=20
recommended guidelines so you don't get hurt.  I'm switching my GF%'s back=20
now...

 inconsistent (I'm just asking, not trolling for flames). >>
