Properly sealed 'dust' caps can and do build air pressure behind them- ever tried to loosen one and have trouble? That says to me that if air can be trapped, water has no way to get in or out. I can find no reason for a full immersion soak once the dry dustcap has been secured.
Consider the amount of times that cylinders are changed on a boat with sea spray, wet hands- not to mention the cringe-worthy blowing of compressed air to 'dry' the cap and sometimes even blowing directly in to the first stage.
I wasn't aware of the Atomic seat- the only reg I knew of that 'needed' pressure was the Sherwood.
Pressurised is best for any reg.
If you can tolerate the temperature on your elbow, it isn't hot enough to damage o-rings or lubes.
