Deco stage set up

It's not really DIR specific. Sharing a deco gas means you both get out the water in a reasonable time rather than one diver in forever and another out quick. I would have thought that was obvious.

I don't see how much more clear we can make it. You asked whether the dive can be completed, stages moved and carried without support divers and the answer is yes.

Support divers are there in case things go wrong - in addition to prudent gas planning in the first place. They lug stages around a bit to make the task easier for the gas divers and in this instance take empties away. If a support diver does not appear the gas diver just carries their own crap to the surface and has enough gas to complete the deco. No big deal.

There need not be a corralation between helping someone out in water and reliance. We plan ocean dives on a basis of carrying everything we need - but in water support just makes life nicer. It is supposed to be fun after all.

Read the reports, draw your own conclusion then come back with your recommendations. I would be keen to read them.

Ahhhh statistics.

Did you know out of the last (i think it was) four OC divers who suffered an O2 tox as reported on the BSAC incident list. ehhhh Four of them were diveing stages left and switched to the wrong gas.

Equipmnet configuration is not the only cause of accident although some rigs are obviously inherently dangerous

I have to agree.

Whilst we don't have the luxury of actual support divers we prefer to use an ascent line and deco station for much the same reason. Your surrounded by divers who have gas and can help out.

I hated it at first but i would prefer not to do 70m+ without it now.

Its a nice feeling and as Clare said its supposed to be fun after all.

You are pulling it from air. There is no evidence to justify your statement in the BSAC incident report. I'll remind you that the statement you're trying to justify is:

I have no idea where you have got this from. The evidence you're presenting is one case where a guy a) forgot to turn his pony on, and b) failed to react calmly in a stressful situation. I can't believe either of these factors were the result of "diving systems/configs/procedures they have designed/developed themselves"

So the support divers are redundancy for redundancy, it's all clear now.

Yes.
