Questions on Overhang/Cartridge Alignment using Dr Feikert Protractor on VPI Classic 3

So I recently bought a used VPI Classic 3 that came with a low hours Soundsmith Zephyr 2 cartridge.

I wanted to make setup as accurate as possible so I bought the Dr Feikert Protractor.
I first make sure that the Spindle to Pivot length was correct which I read online was supposed to be 258mm.

See pic below.


This was measured by taking off the tonearm and measuring exactly from the spindle to the bare sharp point of the unipivot point.
After that was done I mounted the cartridge to the arm and got the step 1 in perfect bullseye.



Step 2 however is where things get off.   I'm coming up about 2 mm long on step 2.



Step 3 is also off as its about 1.25 mm short of the line.

Here is a shot showing approximately the location of all 3 points.



Any ideas on what I can do to fix this where it hits all 3.   I'm at a loss being that the Spindle to Pivot point is right on at the 258mm length which i was told is correct for the VPI Classic tables.
Thanks for any assistance you can provide.

The MoFi Geo Disk does the trick for me!!

I own the MoFi Geo-Disc for more years that I care to remember.  It works fine, but it isn't the most accurate device.

The two things I don't like about it is you have to sight align a black ridge to point to the center of the tonearm bearing.  Most tonearms this is fine, but with some tonearms it isn't always obvious where the center of the bearing is.  The second is that it's a one point alignment.  Which means if you're a little bit off in sighting the center of the bearing, your alignment will be off even though you're aligned to the single point on the Geo-disc.

I do use the Geo-Disc to set the initial alignment, but always check it with a two point protractor.
