Hi,
I have been a lurker on this list for a few months, and have found
it (usually) a good source of information. I have a couple of questions that
would be best answered by the WKPP (but all opinions welcome), if someone
could oblige me. In particular I found the reply about why stage bottles
should be on the left of particular interest, so I am hoping that I may get
a reply of similar quality. Forgive my ignorance on these matters but I am
just trying to learn to dive safer.
1. I have seen 80/20 nitrox described as stroke mix, and I am not quite
sure why. Is there a particular problem with 80/20? How about other mixes
such as 50/50, 60/40, 70/30 or even 100%? I have been using 50/50 since I
can come onto it at around 60ft and I feel it is important to try to reduce
or prevent bubble formation, rather than trying to remove bubbles that have
already formed. Is this a reasonable strategy? I have tried to search the
archives for discussions on 80/20 but didn't turn up much of use (its
probably there but I couldn't find it).
2. I believe that the WKPP have developed deco schedules/techniques that are
rather out of the ordinary (but haven't been made public yet). I am
wondering if these schedules have any relevance to the diving I do, or are
we talking about very long and deep dives with extended deco times such as
the WKPP do? (Most of my "deeper" diving is in the 100ft to 160ft range in
open water, with bottom times that would usually not require more than about
15-20 min deco). Basically I am wondering if the WKPP have developed
anything that would make my diving safer, from the DCS point of view. (I
appreciate that you may not wish to reveal all yet but I am curious if there
is something in the pipeline that may benefit me in the future).
3. I gather that the WKPP are using deep stops (since they are on ZPlan).
This concept seems to make a lot of sense to me. Do the WKPP see this as an
essential element of deco? Has this strategy been effective in reducing or
preventing DCS cases. For the shallower dives (eg 100 - 160ft) that your
support dives may do are you also using 'deep' stops? Has anyone empirically
evaluated "Pyle style" stops versus "WKPP style" deep stops?
4. Just wondering what the origin of the word 'stroke' is? (I understand
what the term means, but were did it come from?)
Thanks in advance to anyone who may be able to help me with the above
questions,
Dave
