BGS publishes no centering figure for NM-MT+ 8.5.
On the published front lines alone: 57/43, 58/42, 60/40 — better than the NM-MT 8 line but not the NM-MT+ 8.5 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.
