Been a bit busy while I had lunch folks?

The procedure is to do both though - while you're signalling with one hand you're shutting down what you believe to be the failed post with the other. If that doesn't work you isolate. Isolating at the same time is going to save gas if your neck o-ring or manifold has gone bang or you've shut the wrong side down. In any case as Clare says you have reserve gas across the team so preserving every last bit of your own is not vital.

At least in the dark your buddy can follow your light back to you if necessary. If you've dropped your torch or moved it while you manipulate the valves then it may be difficult for them to work out where you are once they spot your light has disappeared.

or 1 hand closes manifold then moves onto next valve and so on, closing valves individually, one by one. |
True, but it's splitting hairs really isn't it? You're most likely to have a failure on your right post (speaking DIR stylee here). Next up I guess would be a left post failure. Failures that
need you to isolate would be less frequent wouldn't they? So by isolating first you could argue that you're guarding against the infrequent failure first.
In any case it's all b*ll*x - if you can shut your valves and isolate in whatever sequence you want in a reasonable time then you're going to have a chance at sorting a problem. DIR is just one such sequence (and I suspect not exclusively used by DIR-only divers)

Not if we groom you first
I can see this is going to be a most entertaining trip

...except you don't want the OC bit of the holistic approach or to use the same kit as your team in the team approach and don't want to open your eyes to diving OC in a DIR stylee
I guess you just have to accept that 99% of the GUE training is OC based, so if you really do want to do a course then you'll have to do it OC. If you just want to find out more about it outside a course there are other ways

Hmmm, looks like the PADI studying is starting to damage the DIR probe
