Tom

It is a good report. See http://www.capt-jt.com/Dive_Stories.htm to read
the report. The most interesting point was the impact of the gas switch
at 190 FSW to the 21/35 and the impact it had on you. I know that Bill &
I did not notice any impact on that same gas switch. I agree with your
assumption of the FN2 level change and narcosis going from a 10/70/20 to
the 21/35/44. I am also a firm believer in the "State of Well Being"
that each of us have on any dive and in life. You and JT used a four
deco gas plan where Bill & I used the same bottom gas with a three deco
gases plan of 190' (21/35), 70' (50/50), and 20' (O2). We had about 8
minutes of BT. I do not remember what you and JT did.

I know that compared to many in the WKPP, AUE and some others that 8
minutes at ~360-380 FSW is a bound dive, but it would interesting to me
to get others view on this and maybe the impact on standard mixes to
avoid what you experienced.

What was your BT profile on this dive?

R/David
