A few recent things has me thinking about this
This thread https://www.scubaboard.com/communit...cozumel-until-chamber-bill-paid.563018/unread specifically where a few talk about DCS hits that occurred within recreational depths but they don't say what caused the problem.
This thread Where Is Your GF? mostly because I don't have any understanding of GF's
And finally on a recent dive: I had been in the water more straight days than the DM, both breathing same gas, 32% up until this dive which was on air. I have a G2 set at MB 0, she had a Shearwater set at ?? but she said it was conservative as she's had DCS before. Plan was no deeper than 110' (Cathedral in Cozumel) hit 10 min to deco and we'd get shallower. During one of the swim thrus at 100', my computer says 9 min to deco but we were ascending, we had meet another group coming in the opposite direction (plenty of room) and I commented to her after the fact that I'm glad we didn't stop as I was at 9 minutes, she said she was at 6 minutes at that time - this was pretty early in the dive.
This was the first dive I had spent "time" at depth and was glancing at my computer a lot - paying attention to how the NDL time changed as depth changed, sorta watching gas consumption, that kind of thing. Never at any time was I close to entering deco per my computer, but was closer when looking at her computer so....
These DCS accidents? Are they mostly due to rapid accents or not paying attention to the computer?
That leads us to the computer - trying to avoid the Shearwater/ScubaPro debate but - how do you know what setting is right for you? This certainly can't be trial and error based on if we lived or not. I want to believe it has to do with the type of diving we are doing and physical condition of the diver etc... But how and why?
The diving I currently do is recreational, greater than 95% of my dives I'd expect to be shallower than 80' with gradual accents staying well out of deco range but there again, where is deco for me and what settings are best for safe but not ridiculously conservative?
