The adjustment customization labeled "A" in your picture is for cold pressure only and is typically an indicator that the WUR is failing. There is no need to change CCP specs on a properly functioning WUR.
930 CIS does not compensate for altitude, that is done using the idle adjustment screw. If your altitude changes significantly, which is not a normal thing, you may need to give it a tweak same as you would for a carburetor.
964Turbo CIS does compensate for altitude. The -160 and -164 WURs have an extra diaphragm that sees atmosphere and deflects accordingly. Using one of these will solve the problem if you live in the mountains and frequently change elevations. The CCP and WCP should be close enough for a plug and play if using a -145 fuel distributor. A tweak of specs would be beneficial if using a -037 or -016 fuel distributor.

Yes, I think screw B was for a gauge. I'll hit up Jacob. I think the car is fine at 5k feet, but some of the mountains here go up to 10k+, and I had a hard time starting the car when I got up there. I'm thinking the idle mixture might be all that I need to adjust but that is counter to several other postings I've read. Another thing I'm thinking of is going with a Zork tube, which I've been thinking of and which would make it run a little leaner by default.
