I don't understand this at all. He said he sets his computer to something close to pure Buhlmann, never exceeds it, and then hangs around for an extra long safety stop. That's all he really said. How is it "Going into deco with extra steps" if he never goes into deco?
On the other hand, here is a procedure I described years ago that got me into trouble because one user got all hot and bothered by it. When I was deco diving, I used a GF high of 70, which is very cautious. When I did a NDL dive, I never changed my GFs because (1) I am lazy and (2) I know what the numbers mean. That means I technically went into deco on an NDL dive before others did, but I knew that if I had just changed the settings to a higher GF, I would not be in deco. So was in deco or not?
I just did what the computer said was a deco stop at about the same time other people were doing their safety stops, and usually my deco would clear before they were done with their safety stops.
I don't do that anymore because people who do not have the mental capacity to understand these things get all upset if I talk about it, and, who knows, maybe someone might look at my wrist late in a dive and have a coronary.
