SGC vs. PSA expiriment
make sure the submitter doesn't have any "friends" at either PSA or SGC, although I suspect this issue might be evident at only one of the TPG's listed. It would be cool to see this same experiment done first by the average joe and then secondly with a big dealer/AH submitting the cards to see if there is any validity to the argument that the big guys get preferential grades.
Also, crossovers aren't unbiased because the one TPG can already see what the other one thought about the card (good or bad).
