You are kidding, right? There is no deco that works for air diving, and we
don't do that in the first place. "Certification" is bullshit, most of the
WKPP was taught by me and is not "certified" per se. It takes about 5
minutes to teach somebody about gas diving. The agencies have you buffaloed.

"Give me an exact dive that you want to do or are doing and I will give you
and exact run for it as I would do it."

George.

Could tell me how you would do the following dives: 25 min and 30 min @ 50m
and 55m.

These are relatively short dives compared to some of the stuff you do but I
would like to be able to use the knowledge you have acquired about
decompression.

The profiles dives above cover almost all of the diving we do in the Sydney
area.

Deco gas is nitrox 50%, bottom gas is air (until I can find an instructor
who teaches a trimix course I'm happy with).

Billy Williams tells me that Andrew Georgitsis (spelling?) was planning to
come out to Australia to do some trimix courses sometime in the near future.
Are you aware if GUE teaches the deco methods used by the WKPP.

Thanks in advance

My deco is in the text of the stories. We have been recording these now with
the Suunto computers set to gauge mode. We download those and merely write
down the run times for each gas change. Hunsucker will be publishing all of
that. I did not want any decos put into the dive reports on WKPP or the GUE
site unless they were identical to what I prescribe to avoid confusion. It
is interesting that the guys who do not do it my way always have a worse
result when tested.

The dive profiles you are asking about come under what I call the "minimum
deco requirement", meaning that they will not appear as proportionally short
as the long profiles which hit saturation. Give me an exact dive that you
want to do or are doing and I will give you and exact run for it as I would
do it.

Hi George,

Let me introduce myself first as a recent observer on
the list and a recreational/ weekend tech diver who
dives in the warm waters of the Philippines, run times
rarely exceeding 2hrs.

I was very interested in following the thread on
oxygen management during deco and the descriptions of
your pioneering profiles as you mentioned.  I had a
quick surf through the WKPP site but could not really
find profiles as such.  I saw your standard mixes and
summary dive reports giving depth and bottom time.
Please could you point me in the right direction to
where I could find your deco profiles/ running times.
I am particularly interested in your shorter dives!
Say, less than 330 ft and bottom times in the order of
30 mins.  For example looking at the dive reports for
2000: Feb 5 Sally Ward Spring 245 ft for 25 mins or
June 23 Wakulla 280ft for 25 mins.

Thanks in advance,

Osman Tosun.
