What Deco Algorithm do you use? (Poll)

[Jax]

Man! But I am confused. Don't you guys use computers?

Or are you contemplating writing your own programs? Cause frankly I think the way people feel is so anecdotal and subjective that you could spend your remaining days varying your conservatism and M values and never think anything changes.

You see, that is why *I'm* confused. My bubble model algorithms don't produce anything like the table produced in the NEDU study. So, I would like to see what their algorithm is . . .

I understand the algorithm Uwatec uses, and have been able to simulate it so I understand how it works. So, the BVM(3) model . . . I don't get it. The 70fsw - 40fsw stops add over 45 minutes of bottom time . . . and therefore more deco time.

I am confused on how they chose such a model.

Didn't you watch Joe Dituri's deco talk? Actually nobody really understands deco theory. Dr Zumrick (a generation before Dituri) always said that there is no way to mathematically predict DCS, and I don't see that anything has changed. I use what was recommended by Shearwater (30/70 IIRC), and follow it. I have never had a problem (knock on wood). I tried cutting tables for awhile, but caves aren't like the ocean. You don't get to pick a depth, and go to it, then ascend by the tables.

Perhaps you may want to consider emailing the authors directly.

Yea. Based on the papers I linked and the conversations I've had, that's correct.

Less deep time, more shallow time, and more time overall.

.... heading directly towards the failed A2 NEDU profiles.... hypocrisy in action - got to love it.

I did, of course, and deco theory is a crap shoot.

That doesn't mean that I should not want to understand the argument and discussion. I recognize many others don't care.

I will do that, once I have educated myself enough to ask a (some) logical question(s). It's unprofessional to expect a one-on-one 'teach me' discourse. They deserve an informed audience.

Ross's two posts on CDF:

1 to peddle his software
1 to snipe at the NEDU study.

Do the heavy hitters really have to come to third (or was it fourth?) forum to lay it all out and make you look like a clown again? I guess its been a few months and you've had time to forget how embarrassed you were.

Chill, please. Let us have a respectful, even if disagreeable, discussion.

Hmmm, and both posts in violation of rules. rossh, consider this a warning. Rule #2 No Soliciting, Rule #6 Comments about individuals, agencies, organizations, political parties and businesses will be removed if found to be inflammatory or cause the discussion to be uncivil.

You can't seriously go after him for something he may or may not have broken five years after the fact?
