Can anybody provide any insight as to why there are sets on the Registry with a 10.0+ GPA?

No logic to it. If your scale is from 1 - 10, it doesn't make sense for a set to have a GPA above 10. Getting the weights in line would have made more sense. On master sets completion % should carry more weight than one person having some "10's" and the next person having some "9's". If you want to add bonus points on set rating, that's fine, but inflating GPA makes me scratch my head.
For example; I was looking at some of the weighting on the 1960's Bazooka cards and noticed that when the population numbers were similar some of the weights were significantly different. I have also always been confused by the weights given to the OPC and Venezuelan issues. Giving bonus points for "10's" seems to punish collectors who focus on condition sensitive issues. As it has been said many times on the boards, there doesn't seem to be that much difference between many 9's and 10's.
If the weighting on these cards are "wrong" it's going to make the set rating wrong. In my way of thinking, weights should be determined more by statistics than opinion, that way a truly "rare" card that was a "7" would be rated higher than a "10" in a card that was not as hard to find in a 10.
