    Suppose a dive profile has a pDCS of 1.33 on best mix. Suppose that getting bent is very bad with a 50% chance of death due to location etc.

    Would you do this dive or use a deco mix to reduce the pDCS?

    Why does the title say pDCS=0.66 but your post says pDCS=1.33 ?

    What is pDCS ? What determines that number?

    probability of DCS. based on empirical evidence from dives.

    50% chance of death means this would be a serious type 2 hit. current navy guidance is 0.1% for type 2, so it would be 6.6 to 13.3 times more risky.

    more deco and have a contingency plan for IWR.

    Do you mean 1.33%?

    None of this makes sense.

    That’s a lot of suppose,s why not simply name the dive and the reasons for it. No one is going to take a risk without a reason.

    Say it is a model that results in that probability. This is a question about risk acceptance.

    Are you saying 1.33% pDCS and 0.66 pDeath too high?

    time for some education on pDSC and its computation etc. Im always open for learning something new.
