Lets re-think.
For visuals look at your owners manual page 7 , fig 6. , Tonearm/Spindle Layout. All Graves reported is that if your air manifold that holds the spindle is ever so slightly cocked to the "northerly" ( to the top of the page) or southerly ( to the bottom of the page) , the Tonearm/Spindle's relationship to the alignment guide has changed.
In a cocked position , the tonearm's relationship to the fixed position of the alignment guide is off, thereby, all other adjustment's are subject to error. Bring the manifold into proper square in relationship to the plith changes the tonearm's-headleshell's relationship via the fixed position of the alignment pin, thereby, all headshell cartridge adjustments made are now more accurate with less a chance for error.
Less error , less distortion, less cartridge wiggel more music. A fraction of a degree change in the position of the arm manifold ( ie squared) is the key to extracting the last ioda of sound from the 'Noll.
Graves noted that this and other adjustments need to be re-checked. A protractor/ruler or a T a square make the job a breeze. One can even "eyeball" the adjustment.
The challenge is getting access to the bolt-heads on the underside of the plith that usually means breaking the table down to make the adjustment easier to complete, re-assembleing the table before the other adjustments pages 8-15 can be completed.
