Therefore doing multiple purges would probably be required to reduce water vapor to a negligible amount to make a difference in pressure/performance.
I am being anal here, but a tire pressure gauge reads gauge pressure and not absolute. So technically 30psi is three ATM .

I agree that multiple purges are required to get most of the water out.
