Which centering ratios reach exactly a BGS 9.5?

On the published front lines alone: 52/48, 53/47, 55/45 — better than the Gem Mint 9.5 line but not the Pristine 10 / Black Label line. Corners, edges and surface can only hold or lower the grade.

How is the ratio measured?

Compare the two borders on each axis: a card whose left border is 57% of left plus right is 57/43. Services judge the worse axis, front and back separately. SlabbyPrep measures both from a photo to a hundredth of a millimetre.
