Too simple.  Vanilla troff (the one that produces codes for the CAT/4)
outputs some initial lead before the first page boundary.  Unless you
take the first tic mark as a reference point for the top of the
document, all of your pages will be printed about a half inch (I'm not
sure of the exact figure here) too low on the page.
