I finally get it!

Right. I wish more would realize this. Not as much for their own sake. Anyone wants to spend more money on protractors than stuff that actually makes music, and more time obsessing and fussing over microns when the dang thing ain't within millimeters most of the time anyway, that's all fine with me. To each their own. 

But unfortunately new people come along and see this and conclude playing records means having to do all this crap. Happens all the time. Then they either sit there looking at the ten grand rig waiting to pay some dude to come set it up, or decide its just not worth the hassle. Which is a shame. Because its not a hassle. Its easy. But who is gonna believe that when the guys who want to make everything just as hard as it can possibly be are sucking up all the oxygen in the room?

A arc protractor is free.
As downloaded SW and you put in your specific TT S2P distance.
And you chose what mathematical equation that you want (Löfgren A/B, Bergwall or ..)
Print it out, check distance of the printed result to ensure it is in scale.
Done.

As for azimuth I were one of them that obsessed to get my setup as good as possible. After reading people setting up with special test/calibration records. And with special equipment (fozgometer) or computer software. I also used digital oscilloscope and so on.
Read people that had many different pressings of Denon calibration records + other brands of calibration records. And they come to the conclusion that every single calibration record measure slightly different... And remember supposedly when making a calibration record they hopefully make all the angels setup on the cutting lathe as good as possible.. and we end up with variance anyway..

So should we set up perfectly against one calibration record? What is then the result.. .. that we only have a perfect setup on THAT record that mimics just that particular angle that the cutting head had when it cut just precisely THAT laquer..

So the lesson was azimuth vary from album to album. And if we suppose that the cartridge manufacturer has done as good job that they can do. Then it is just to put your cartridge for azimuth as horizontal as possible. And in a average between albums it will be the best.
(If it is not damage/faulty in any way)

Thanks @boxer12

You can always widen the hole a little so you can move the arm in the right direction then tighten it down.

..one thing to add.  When setting the cartridge in the right spot on arc protractors with slotted attachment head, you must be able to make sure the cartridge is square to the arc (or as best as it's possible) or the alignment will be off. That's the reason I use the MINT, it makes this adjustment doable if the instructions are closely followed.
