Subject: Latest Horror Story - Rule Number Two
I notice in the latest horror story that 32% was used up to 80/20 
(strokemix) for the deco. I have already pointed out the stupidity of
80/20 in another post, so will not beat that dead horse. I will ,
however, drag out another old dead horse that I thought we had already
given a sufficient beating, and that is the low ox is no ox bendomatic 
schedule.

 We discovered at WKPP that when we used one ox, like anything 30-40
percent from anywhere like 90 to 120 up to the oxygen tanks, we got
bent. We found that inserting the 50/50 from 70 feet through 30 made all
the difference, with or without the low ox.

 For bounce dive planning, like what most people do, you are better off
picking the 50/50 and skipping the 32-35 if you are chosing. 

 Better yet is a trimix deco gas from whatever up to the nitrox. 

 The tables we got hammered on where Hamiltons. We told him, he fixed
it, that was years ago, but now I see this stupidty has resurfaced.

  The problem is that the guys who really do this are never used as a
source of infor for it.

  Rule Number Two is "Don't Listen To Strokes".
