What "qualifies" as a "real photomatch"?

[soxfan]

Hi everyone,

So in looking at the Sheffield possible photmatch thread...it got me looking at my stuff, and I had posted a possible photomatch for my 2008 Jed Lowrie bat and most thought it was close but did not qualify as a match....what is the qualification boundary as to when it can be considered a "true photmatch"?

Opinions....as there are so many members who have so many more years of experience than I do (yet another reason why I love this site!)

Thanks
