I am not Butting in, BUT...for someone without PFO and fully hydrated, this
dive doesn't require deco-only 20fpm ascent and a few seconds (a minute or
two at most if its not first of the day) at 10ft to get your self together.
AND don't start with "my computer..." or "my software..."  I just did this
last Sunday, Mexican Pride 130fsw bottom and 90 fsw on top. Two dives (32
min and 44 mins with 40min surface time) No deco-slow ascent-and I pulled
the anchor up one side and 40 ft away over the other side. Shot 180 pounds
of fish. 29% eanx.
    If u have not been tested for PFO then its a different story. This also
depends on how you r defining bottom time.I have never been to a
chamber(other than to visit) And I am only applying what I have experienced
and experimented with on myself. I have been following Irvine, Jablonski,
Weinke et al for 8 or 9 years, Understanding Georges explanations will give
u more information/education than u could ever pay for. Your Results May
Vary -EZ

p,s, this is not what is taught thru agencies-this is what happens in the
real world-it has nothing to do with what I have to teach.
