That thread is helpful, though some of the pictures have disappeared (maybe they were linked in a photobucket account, and deleted?). I do know there has been at least one discussion on the CU boards about the PSA flips that was not deleted or closed. I refer to it from time to time:

Doug,
Respectfully, I did not miss your point. I wouldn't be asking a third party to compile this information. This is something I'd take up on my own. I spend a lot of time looking at cards in auction catalogs, on Ebay, comc.com, private collections, etc. Once I've confirmed the number of flips that have been used, it should just be a process of creating a list of serial numbers, and documenting which graded cards were issues with which flip.
If I see a PSA graded card with a serial number of 6122122, and another with serial number 7122122 (both employing the same flip style), then I can reasonably assume all cards within those numbers use the same flip. It would just take some time and patience on my part.
