If you start cross comparing, who is going to be the judge of the companies that you do and don't include on the comparison. Someone can include both SGC and PSA, but then by omitting the one BVG card that ranks higher than both of the first two companies, that is misleading also. Then if you include BVG as well, the KSA owner says, "Well, what about MY 1 of 1 KSA 10!?!?!". Just gets to be too much. I see nothing wrong with sticking to the single companies pop report. When you start crossing companies report like that though, I just don't get it.
