How do you judge Tag Team Centering?

I have a hard time assessing tag team cards centering, so I thought I would ask you all for help. Do you think something like this has good centering, and is it worth grading if its otherwise flawless?

I could be wrong, but I believe you’re supposed to measure the silver borders, not the black lines.

To me this looks top heavy, and I would guess it gets a 9. I tend to be pretty strict though, so don’t take my word as fact by any means.

I usually do the distance from the outside of the black line to the edge. With that this card looks top heavy.

Full disclosure, I’m still unsure if there’s a more official way to do it, but that has done me pretty good for judgements

Isnt this the same thing?

I don’t think so. I’m saying measuring the thickness of the silver border from the edge of the card to the beginning of the artwork, ignoring the black lines entirely.

But I’m sure there’s several methods people use effectively that differ from that, was just offering mine.
