Questions

What centering does ACE require for its top grade?

Gem Mint 10: under 60/40. ACE does not say front or back for its 10; applied to both. A card exactly on the figure does not meet it.

How is centering measured?

Compare the two borders on each axis (left vs right, top vs bottom). A card whose left border is 55% of the left+right total is "55/45". Services use the worse axis.

Does ACE publish back centering figures?

Yes for some grades — see the table.
