A 7 1/2" pin to PAP, I would see that as a 6" pin from the NAP. You can disagree with whatever you wish....it is what it is.
And of course my question would be why would you need a 7 1/2" pin to PAP. Secondly, if you use the original Patrick Girard layout, which is a 5 1/2" pin from the NEGATIVE Axis Point 1 1/2" below the thumb to control the bowtie. It is PLAIN and SIMPLE.
