They use a sight line to line up to the pivot point. That's what Garth's string was intended for in my best guess-timate.
Once you sight line the pivot, then you can use the protractor for lining up the grids.
With Ken Willis at the helm, he can compute the actual tonearm you are using and build an arc for that specific tonearm.
No guess work is left because there is no sight line to verify.
What the pics don't show is the very soft clear plastic laminate over the firm board. The plastic laminate allows a soft resting place for a stylus. I like it a lot better than the hard plastic turntable basics surface.
Its the little things that count.
