500 psi is a good plan for those who do not want to put any real effort into planning. And I can live with that as a planning tool.
When it actually comes time to get out of the water, my standard is it is a fail if I can't still breath from that tank. It is rare for my tank to be less than 500psi but I also have little problem with 300psi. I avoid diving with ops that would even notice that small difference.
Regulators will behave differently at low tank pressures. Balanced 1sts and 2nds will generally be less effected than their unbalanced counterparts. My Mk7 (honker) is different in that it basically shuts down breathable gas to you primary around IP. A diver must switch to the alternate. It is good to take your rig down to "empty" just so you know how it will perform.
IP is not OOA.
