Sorry, no I wasn't trying to feed you anything that distasteful. I'd
read the stuff you posted previously, but when you talked about "discard
the 10 foot silliness" I had assumed you were talking specifically about
O2. Thanks for clearing that up. All this is really appreciated.

You are kidding, right? I explained in detail how I would do that deco.
Please, please , please stop feeding me the IANTD party line on deco and
read the stuff I wrote. It is all there.

George,
Karla's example was for deco on 50%. Your changes give 8 at 20' and
nothing at 10'. Is that for 50% also, or are you assuming O2? If it is
50% why no stop at 10'?

Subject: RE: Standard Deco Dive
I would make the following changes: slower decent, then after 20 at the
bottom, ascent at 30 fpm, consciously stopping every ten feet to achieve
this, then stop at 120-80 for 30 seconds each.
At 70, the gas switch, I would do 3 minutes to get the full effect of
the switch. See the post that talks about circulation time.
The 3 minutes each at 60,50,40
5 at30
8 at 20
ascend to 0 in 3 minutes
I notice you make a comment about the line. Get in the habit of
consciously stopping every ten feet to insure the proper ascent rate.
Coming up from depth too fast is what gives you the subclinical symptoms
hours after the dive. You trap gas in poorly perfused areas and these
later swell and react, the bubbles in them grow, the reaction presses on
nerves, and you get things like numbness in some extremities while you
are sleeping that night - not a cns hit, a cns manifestation. Skin bends
would be a more obvious consequence of skipping deep stops.

I'll bite on this one.
My typical dive is to 165ft. 20 minutes bottom time. I use a 35/20
helium mix.
My deco is on 50% starting at 70 ft.
I do a 1 minute stop at 100 (run time is 22 minutes)
1 minute at 70, while switching gas.(run time is 24 minutes)
1@ 60(run time is 25 minutes)
1@ 50(run time is 26 minutes)
2 @40(run time is 28 minutes)
4 @ 30(run time is 32 minutes)
7 @ 20(run time is 39 minutes)
18 @10(run time is 57 minutes)
I observe coming up the line slowly, hand over hand. Probably about 30
ft per minute.
Karla
