NM/Mint 8: 65/35 front. As published: "For sports and non-sports cards, centering must be 65/35 or better."
CGC publishes no centering figure for NM/Mint+ 8.5.
On the published front lines alone, a worst axis worse than 60/40 and up to 65/35 meets the NM/Mint 8 line but not the Mint 9 line. Of the ratios with their own page: 65/35. 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 reads both from a photo and shows each border to a hundredth of a millimetre; on synthetic test photos, 97% of the readings it shows without a warning are within 1 percentage point (the methodology page has the full results).
