VDGM is referring to a dive I did a year or so ago, where I was in a tremendous hurry because I was late, and missed THREE separate times when I normally check my pressure before I dive, including the fact that the "team" check didn't involve reporting actual pressure, but just a verbal confirmation that each of us had enough gas for the dive.
After we got underwater, I checked my gauge and discovered I did not have a full tank. I immediately did the necessary calculations and concluded that I still had plenty of gas to do the dive we had planned, and I did, and we did that dive, and it did not have to be made shallower or shortened because of my mistake.
It was an error, an individual error AND a team error. It has happened once in almost a thousand dives. It made me even more meticulous, and also made me very resistant to being hurried into the water.
I fail to see in any way how this is related to going to 200 feet on a single Al80, ON PURPOSE.
