Hi All,

I think JJ's origional tables got all screwed up (at least in my in my
inbox).  I think this is correct, I put in tabs to separate the space and
used courier font for the tables.  The total times don't exactly add up for
G's or JJ's so maybe I'm missing something.  The first one does add up to 88
minutes.  Here's what I got.

I then for chucks and giggles ran the same profile using Decom and deep
stops.  I first used the default settings then straight Beauman (SP?).
Here's what I got:

Here's Decom using 5% for N2 and 14% for He (out of the box settings):
Depth Time O2/HE/N2
  150    1 16/50/34 
  140    1 16/50/34  
  130    1 16/50/34 
  120    1 16/50/34  
  110    1 16/50/34 
  100    2 16/50/34 
   90    4 16/50/34  
   80    7 16/50/34 
   70    3 50/ 0/50 
   60    5 50/ 0/50 
   50    5 50/ 0/50  
   40   10 50/ 0/50 
   30   11 50/ 0/50  
   20   19 100/ 0/ 0 
   10   28 100/ 0/ 0 
A whapping 99 minutes of total deco time!  Without the calculated deep stops
the total deco time is 92 minutes and you start at about 130 feet.

Here's Decom using 0% for both (straight Beauman (SP?)):
Depth Time O2/HE/N2 
  130    1 16/50/34  
  120    1 16/50/34 
  110    1 16/50/34  
  100    1 16/50/34 
   90    1 16/50/34  
   80    1 16/50/34 
   70    1 50/ 0/50  
   60    2 50/ 0/50 
   50    4 50/ 0/50  
   40    5 50/ 0/50 
   30    7 50/ 0/50  
   20   11 100/ 0/ 0  
   10   18 100/ 0/ 0 
This time only 54 minutes of deco.  Without deep stops you have a total dive
time of a scary 48 minutes and the deep stops start at only 80 feet.


I thought some might find this interesting!

	Thanks for your interest. Anthony, can you post to the list your
time line on this. My guess is that it should easily be done this week.
Price is $89.  GUE members get discounts based on their membership level.
When coupled with the other discounts and benefits membership is actually a
very inexpensive option.
	Best,
	JJ
