I got a chuckle thinking about GC having a history of being more nannyish. I don't doubt that but just thinking of my own early experience diving GC in the late 70's where on a two tank boat dive we would hit depths of 120-130 with deco stops on dive one, a beer on the boat during our si and the shallow 2nd as long as we want until 300 psi. Not advocating this but have fond memories.
