    Question What Deco Algorithm do you use? (Poll)

    DECOMPRESSION CONTROVERSIES - Dr Simon Mitchell Briefing (Video)

    Wondering what algorithms you use, and why?

    not quite 40/80, but certainly favor shallow stops. With a controlled ascent profile, I don't think there is any reason to be concerned about deep stops

    I suffered from fatigue when diving, and found "Pyle stops" on research. That made huge difference for me.

    I'm not willing to give up my 2-minute midway . . .

    But I let the Petrel's 40/80 rule . . .

    I started cave/deco training with vpm, and I see no reason for me to change to anything else. I haven't done any really long hangs yet, but on +2 or 3 for conservatism I've never felt even slightly fatigued after several dives in the same day. Most of my dives do seem to end up with a profile that causes a quasi deep stop though (front section of devil's, top of the superstructure on a wreck, etc).

    I dive a 40/85 or 40/80. I skip deepstops as I feel better after deep dives.

    Maybe interesting, but in German: https://techdiving-network.de/wp-con...deco_et_al.pdf
    It is about when ratio deco becomes aggressive.

    I wish you had added another category, which is self created algorithm. That is the person who dives any algorithm, but will "pad" stops by adding extra time. If I understand the research correctly, this practice from what I read is fairly common,does have a tendency to introduce other ongassing issues of certain compartments.

    I would be interested in finding information that could be titled "Gradient Factors for Dummies." Something that would help generate enough knowledge to lead into deeper level materials. Any suggestions?

    Thanks,

    I checked "other."
    I don't need any fancy algorithms; I just ascend slowly and stop a while. "I can feel the nitrogen leaving my body."



    ..
    I have seriously known the quoted bit to be said.

    Also: good poll.

    Greg,

    Please check out Dr Mitchell's video in the above thread. Yes, it is long, but he has an excellent walk-through for Gradient factors.
