Just went through and serviced my regs (Atomic) for the first time, and a question occurred to me. Once you have the orifice set, why would you ever turn in the spring pad to increase cracking pressure to the 1.x"-1.x" range that is "spec" on your primary second stage? I can understand de-tuning the octo slightly, but why the primary? After setting the orifice, I've got my reg sitting around the 0.5" range on the manometer and just wondering why I would basically double the breathing effort to spec.
