Hi all,

I haven’t had time to read in the proceedings of the DAN workshop that was linked before. What I saw that came most closely to a recommendation was a report of a plan to do a study trying to bend subjects in a simulated fly after dive scenario. Which is not much that could be put into software. Maybe one should check the Rubicon Archive for more scientific information on the issue.

ok, I did some Rubicon search and follow up reading an the two most relevant papers seem to be 
http://archive.rubicon-foundation.org/xmlui/bitstream/handle/123456789/6255/SPUMS_V9N3_4.pdf?sequence=1andhttp://archive.rubicon-foundation.org/xmlui/bitstream/handle/123456789/5611/DAN_FAD_2002.pdf?sequence=1(in particular the executive summary).
Upshot seems to be: Very hard to asses given the low number of cases (boarding a place when you already have DCS symptoms seems to be a totally different game, though), but 12-18h limits, maybe 24h seem to be a good idea and there is no model on the marked that is able to predict this.
This seems to match my expectations.a) made up random shitb) semi-scientific algorithms, tuned by random numbers without any scientific basis in order to match pre-conceived notions of "this sounds about right"

Did anybody ask what happens at 8000 ft when the cabin decompressed to 40,000 ft  Sure. You are  breathing 100% O2 if you live long enough to put the mask on.  Will you avoid DCS on the way back down to 18,000?
