I guess we need to start this all over again.....

How long does it take to breathe down a 1.6 PP02 loop to 1.2?

Dave

I realize that the last time this came up it was discussed in length. In the end, all of this comes down to personal preferance. Frankly, I was bored sensless after the first 18 pages of the other debate.

To answer your question, it takes me at least 4 minutes to breathe down a 1.6 to a 1.2 (assuming I'm not on my KISS, which would take forever unless I shut off my O2). Unless you have the VO2 of an ox, I can't imagine it takes you much less. Besides, it's not the 1.6 I'm worried about. The real question is how long does it take you to breathe down a 2.5 to a 1.3 or better yet, to flush a 4.0 down to a 1.3? I'm guessing at least half the length of your bottom time.

It was just yesterday that my buddy had to go SCC on his inspo (when we both had an hour of deco remaining), and he woudn't have had any significantly shorter deco on 18/50 than on 10/50. In fact, his deco ended nearly exactly with mine, and I was at a 1.3 the whole time.

Aloha,
