Not really sure what your trying to ask. At 20psi your pressure is 20psi. You need to set the pressure at the compressor to 20psi and you’ll have that at any tool you’re using.

I’m also not sure of the question, and the guns are different, and various finishes do take some tweaking. I also never spray varnish, it is so slow to dry the overspray coats everything in the area making a real mess. Other finishes can dry while airborne and just settle as dust. That said, for my conversion gun I usually have the compressor set at 45#, but then the regulator in the gun is set to 15# when the trigger is pulled. But like I said, I’ve never sprayed varnish.

Tom:
For those of us who spray from time to time, I put a splitter on my air compressor. One side provides full pressure, and the other side provides 35psi air, which is where I run my HVLP guns. I keep the water separator before the split. I also popped for two wind-up reels on the wall, one for the guns, one for general use. The gun hose is a much lighter hose, since I do most of my spraying in warmer weather outside and hose gets heavy.
