Default top-bottom centering on 1954 Topps

Apologies if this has been asked elsewhere, but how do the grading companies measure the top-bottom centering on a 1954 Topps card given that there isn't supposed to be a top border. That is, since 100% of the top border + bottom border is, by design, at the bottom, what ratio are they comparing? And is it the same for PSA as for SGC?
