Pixel Counting - Am I doing this right?

Bosox1976

Trying to make sure that I am doing this correctly.

1. I blow up the picture (zoom) until the picture breaks down into pixels (little squares).
2. I count the pixels on both borders at the worst possible point (in the case of the Clemente 24 pixels on left, 10 on right)
3. I divide 24/34 to get 71% (left), 10/34 to get 29% (right)
4. Therefore side to side centering on Clemente = 71/29

Correct methodology? It sure looks a little worse than that.

The way you described it is exactly right. I use "jruler" to measure pixels on my cards. I measured the Clemente left to right and got 72/28...very close to what you came up with.

That's how I do it. Using the same method with Windows Paint blown up to 800%, I get 11 pixels on the left and 4 pixels on the right, or 73/27. We're all in the ballpark.

Thanks fellas. Method seems simple, but just couldn't believe my Clemente was that close to 70/30 - seems much worse.

Actually, 70/30 seems right. Keep in mind that it means one side is more than twice as thick as the the other. It does LOOK 70/30. I think the perception is that 70/30 is not suppose to be that bad, but it really is.

Great info-thanks for sharing. I came up with 73/27 on this card. I would like to have it graded with no qualifiers. This may be a stupid question but should I submit it slabbed or crack it out? I have never tried a regrade or crossover so I am not sure as to the best practice. Thanks
