That makes no sense. How did I make your point and where are you coming up with the vrfpr giving 18psi? Stock is not always 13 and the adjustable's can be anywhere you want them to be, not stuck at 15!!! There are some stock regulators running 22psi, there's one on my Dad's suburban right now.
I think you need to re-read my post, you might have gotten some numbers mixed up or something.
