Gem Mint 10: ~55/45 front, 65/35 back. TAG says "approximately", so the line carries grader discretion.
Pristine 10 needs ~51/49 front, 52/48 back; Gem Mint 10 needs ~55/45 front, 65/35 back.
On the published front lines alone: 50/50, 52/48, 53/47, 55/45 — better than the Gem Mint 10 line but not the next line. Corners, edges and surface can only hold or lower the grade.
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.
