Questions

What centering does BGS require for a 10?

Pristine 10 / Black Label: 50/50 front, 55/45 back.

Which centering ratios reach exactly a BGS 10?

On the published front lines alone: 50/50 — better than the Pristine 10 / Black Label line but not the next 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.
