1. placement of the SPG on the right hip D-ring. Takes too many steps for a diver to check gas and isn't visable to buddies (so they know your gas supply)
(If you are talking about the left side
...I didn't catch that the first time)
Its a nice clean spot for it. The SPG is a backup anyways. I shouldn't have to be checking my buddies spg. I am not a babysitter, I'm a teammate. He should be able to do it himself...and I expect him to do so and not lie about it.

2 buckle placement , the buckles are placed on every diver the same so the divers buddy can remove the rig in an emergency?. I would never even try to go for a buckle in an emergency. I'd go for my shears to cut the gear off. this crosses every agency and gear configuration. don't look for any buckle! just get to cutting
Cutting off rig in an emergency isn't DIR? Where did you learn that?

3. rock bottom calcs, way to much math and there are easier ways to make sure the team has enough gas.
After you get the concept, you will end up with 3 or 4 numbers to remember. Not a tough thing. The math demonstrates an understanding of the issues involved, but in the real world, a couple of numbers you have remembered do the trick.

4.false sense of security. just because you've trained with the same agency doesn't mean you can count on another diver being there when you need them .
Who says they are trained by the same agency? But beside that, you only do a dive that the weakest member of the team is capable of and all the teammates have bought into the idea that they are a team. This is the biggest thing with DIR but is the hardest to describe.
Being a buddy doesn't mean you are a babysitter (aka...your SPG issue) or being babysat. Anything you do, you must ask yourself "What impact does my action do to the team?"
You want to take a peek in a room and your the second guy in a single file....Do you just stop and take a peek or do you signal your buddy to hold while you poke your head in? Which one do you think is the "DIR" solution?
nova:
5. the pony bottle theory. If you don't need it don't take it ????? how does anyone know the outcome of any dive? I think if you might need it take it , it's your life.
What problems are you solving with a piece of gear?
What Problems do you create by taking this piece of Gear?
Can another Piece of Gear solve the same issue (and what problems does it create)?
What is the probability of the Problems being solved?
What are the consequence of the problem(s)?
Can training (or a procedure) be used in place of this gear to solve the problem?
Every piece of gear should be put through those questions. Then it becomes obvious what should/should not be taken on a dive.

6. no solo diving. well everyone should be able to solo dive . self reliance is a must underwater.
No one says that a diver cannot be self reliant, but that doesn't mean you should dive solo. Do you see the difference here?
