Consider the source ( a "dive instructor" LOL ). Eve, you still have no clue
what you are talking about. If you do not have anything but your usual
whining , complaining bullshit to spout off, take it someplace else.

Why don't you complain about Weinke like you tried to do about me, and see
how far that gets you. You have nothing anyone here wants.

Now we are all starting to see why guys like Weinke will not waste their
time dealing with idiots.

Eve, maybe you can answer this question - why are you on this list, and what
have you ever contributed to anything to do with the subject matter of this
list?

Subject: RGBM GF or JF?


I see so many questions, doubts, and comments on RGBM that I can't help
putting a big grin on my face. Are we putting our lives on this so-proven
model on mere faith?
One instructor showed me a scary comparison made, not against other models,
but on itself.
Has anyone else compared the deco at different depth, same time or same
depth
different times? Well, this instructor did. On a mix 16/(20-40) % for a 20
minute dive:
stop.......220 ft........200 ft
140 ft........1..............1
130...........1..............1
120...........1..............1
110...........1..............1
100...........2..............2
90............2...............2
80............2...............2
70............3...............4
60............4...............4
50............5...............6
40............7...............8
30...........10.............11
20............5...............6
10...........10.............10
total........54.............59min
So similar deco profiles for both depths yield a longer deco for 200 ft than
for 220 ft!
Give me a break!
I understand the "official" explanation for this difference was a higher
degree of "conservatism" due to a higher hit frequency in the shallower
depths......yeah, sure.
The model is perfect; it's the divers fault they get bent!

How much higher a conservatism? Why does it happen again with 170 ft and 190
ft where a 15 minute dive gives a 33 minute deco for 170 ft while only 29
minute deco on the deeper dive? More conservatism or a higher "Jeeezzzuz
Factor" (JF)?

How do you adjust the JF to dive 170 ft for 15 minutes and do a total 33
minute deco or rather dive it for 20 minutes because you only do 32 minutes
deco? You mean a 5 minutes longer stay yields a shorter deco? Yep, it's
right
there in the Naui book, Tables pp 3, 4 and 5. See for yourself before you
trust a model with your body. I have seen the outcome.
Heck, I can develop my own deco model. I've got a dart board too!

BTW Christina, the impropriety of using a government e-mail address for
promoting, selling or private purposes is dealt at a different level. Not
only is improper and unethical, but illegal. I can e-mail you privately on
that if interested. That goes for the private commercial use of government
facilities. But I bet you that at this time, "he is laughing all the way to
the bank".  What is a simple taxpayer supposed to do?
