I have a dumb question about cave training

Well, to quote an earlier post, that's just dumb.

I knew you’d see it my way

I couldn't agree more.

I couldn't agree more.

I won’t bother to even search for current NACD standards, but when I did my Basic/Intro training, you were expected to be in Single tank. I never bothered to buy an H/Y valve and did all my intro/Apprentice dives in double 95s. I remember feeling like a bit of a renegade at that. (Early 90’s) .. Ginnie wouldn’t let me dive doubles with my Intro card unless I was with an instructor. Of Course LR was always the place to go for “no questions asked” diving. Even Peacock at the time had a ranger who gave me a hard time about diving doubles.

I find it interesting that Ginnie one trusts Intro divers to limit to 1/6th, but I can’t even scooter to the Maple Leaf without a cave/DPV card. ....and I know that we’ve had dpv gas management fatalities. But I’m pretty sure we’ve had intro gas mgt accidents too, where I appears 1/6th rule was violated. Peacock 2016?

So....I got curious. Obviously the NACD website doesn't have anything (althought I checked). However, the Wiki page does. Not the most up-to-date thing ever, but the excerpt below explicitly states that "[Intro to Cave] is designed to help hone those skills previously learned in cavern. New skills and procedures are taught which are needed for limited single tank cave penetration."

I think the Ginnie rule was a bit of a knee jerk to the recent-ish incident in there. I think that the Peacock incident was more easy to ignore as it was a violation of standards and a personal mistake as opposed to the Ginnie violation of "standards" that would be taught in a class that person didn't take. I don't think that a DPV class will always teach you to be responsible/competent, and even a well-taught class doesn't always lead to competent/responsible diving. Even today, I'd say that most cave diving deaths are either medical or caused by a violation of the simplest rules we're all taught.
