I think people who carry their mixing machines and software on their backs are cheating! lol
Having access to my own continuous mixer did change my mindset in regard to " perfect mix " for a brief time while I was still ndl diving predominantly. It became a PITA as RJP outlined. When I became comfortable with an obligation and helium, it got to be more about speed and conveniance when it came to mixing.
In the mid atlantic, most diving begins at 75' due to needing to get away from inshore current/ vis problems so seeing anything banked higher than 32% is only for deco or blending, not diving. A divers progression through nitrox begins with extending the ndl to the max as their sac improves. This pushes mixes hotter so they can stay ndl. If a diver proggresses into tech 1 or simmilar programs, the gas back lashes the other way, into safety at depth via a low po2, but accepting a obligation as a way to add safety in the shallow stops.
Also up here due to mission driven diving, be it junkers or hunters we were mentored early about the dangers of pushing the table limits on a ndl dive when a heavy work load, or sac, or stress may be involved. It was another way to add a layer of margin.
When I started going down south I was shocked at the use of hot mixes by everyone when diving easy on reefs ect. By the same token now when I dive down south, I am viewed as diving a hotter mix because their is no mission for me, it is just a sight seeing tour with no rush.
