On the front line alone, a worst axis worse than ~55/45 and up to 60/40 meets the Mint 9 line but not the Gem Mint 10 line. Ratio pages: 60/40.

Mint 9: 60/40 front, 90/10 back. As published: "For sports and non-sports cards, centering must be 60/40 or better for the front of the card, and 90/10 for the back."
CGC publishes no centering figure for Mint+ 9.5.
On the published front lines alone, a worst axis worse than ~55/45 and up to 60/40 meets the Mint 9 line but not the Gem Mint 10 line. Of the ratios with their own page: 60/40. 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).
