I'm also a bit confused why Yip asked you for the P-S distance as the Classic protractor is surely one of his most popular protractors. I ordered mine over two years ago, and at that time there was some confusion as to the P-S distance as VPI does not provide this information publicly. If I remember correctly, what I had differed by 1 mm from what Yip had. You'd think this would be settled by now.
Btw, the alignment with the Mint (at least mine) puts the stylus closer to the pivot than with the VPI jig. And I also ended up preferring the sound with the VPI jig.
