Who disagrees with DIR and why?

[lrmoll]

I don't think it is "too safe." There are many good ideas there and a number will migrate into standard diving as the original "Octopus did" (Safe Second Regulator). I just think some things are carried to a burdensome extreme for the casual recreational diver who never goes deep or into overhead environments. Some things I suspect are statistically insignificant or are assumed to increase safety when they really haven't.

I suppose one can claim that something the increases safety by .000001 is safer but it is swamped in all the other variables that affect safety. In DAN's accident studies they admit that sample sizes and information available is often too small to be statistically significant but it's all they have.

We are all diving today because an organization like PADI thought that simple diving within limits was not as death defying as everyone wanted to think and spawned an industry. If Dir caught on then another agency like PADI
would arise making diving available for the masses again.

Questions:
Has DIR reached the pinacle of safe diving and nothing will change ever again?
Has standard Diving reached an acceptable level of safety?
