Quick MBC controller question

Hey guys, quick question about manual boost controllers. I have a Grimmspeed manual boost controller, from what I understand, every click is ~1/4PSI, 4 clicks is a full pound and a full rotation is 16 clicks (therefor 4 pounds per rotation) I understand how to install, and I understand how it operates, what I do not understand is how the boost is calculated.

If I have it turned 24 clicks (6PSI) does that mean I will be boosting at 6PSI (which is my wastegate level) or does that mean I will be boosting at 12PSI (6+6)

It says you cannot boost below your stock waste gate spring, so I cannot boost below 6, that is fine, but does that mean one simple quarter click is 6.25? 4 clicks would be 7?

basically, is its "Wastegate PSI + Boost Controller PSI = boost"
or is it "Boost Controller PSI = Boost (Wastegate be damned, unless MBC is dialed it is below 6 psi)"

Thanks guys.
