Questions

What centering does TAG require for a 7?

NM 7: ~70/30 front. TAG says "approximately", so the line carries grader discretion.

How much better does centering have to be for a TAG 7.5?

7.5 needs ~67.5/32.5 front, against ~70/30 for NM 7.

Which centering ratios reach exactly a TAG 7?

On the published front lines alone: 68/32, 70/30 — better than the NM 7 line but not the 7.5 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.
