Hi,
If you suffer from some kind of mental failure during a dive but can still understand what your VR3 screen is telling you to do, you would still be able to work out your deco in your head. This would not be necessary (for me) as you have correctly pointed out, the buddy/team would run the deco instead while looking after the mentally failed (or otherwise incapacitated) diver. I should point out that only one diver per team actually runs the deco (calls the shots) the other diver will normally shoot the DSMB and move/stop when told to do so. The jobs could be interchanged easily during the ascent if required as we would all know exactly what profile is being performed.
Before you say 'oooh what about the task loading' we have been trained to handle exactly this type of scenario on Tech-1 and the final two assessment dives are exactly this sort of rescue (from 36m with one guy OOG and the other with no mask. All stops must be carried out including deep stops, gas switches, DSMB deployment and sticking to the run times. Lost deco gas can be thrown in for good measure!) All that with one guy unable to see anything.
DIR divers don't ever think in terms of solo diving. Of course we are very self sufficient (no one is ever entirely self sufficient!) but DIR is all about thinking, planning and diving as a team.
When DIR procedures are discussed they should be kept within a DIR context. IE what DIR divers would really do when diving with other DIR divers, not what you may or may not do if you were using your own personal interpretation of a DIR idea or procedure within your own style of diving (not you personally Mark, but in general).
Regards,
Mark
PS. It is a great system
