Why are PSA's new population reports so inaccurate?

It's in pretty sad shape Kevin, I just looked up a Mordecai Brown card that has had two PSA 5's sell in the past couple of years as shown on Card Target. The Pop reports shows no 5's in existence. I'm at a loss as to how that can happen.

Are you using the straight page for T206 or are you doing the search engine?
http://www.psacard.com/Pop/T206

Make sure your browser is up-to-date or you might not see all the coding they added recently.
There are approximately 180 Mordecai Brown (~60 in each pose) listed. Use the drop down [+] to the left of the name to see all the different back breakdowns. They also now have three lines for each "card": the top line is for the straight integer grades (e.g. PSA 6), the second line is for half grades (6.5), and the third line shows the ones with a Qualifier (6MK).

Supposedly they will roll out a new Pop Report and search engine in the Spring, according to Joe Orlando's latest message.

John, I used the same report as you have in your link. I do have to correct myself, there is only one PSA 5 that sold within the past few years shown on card target (the other was SGC). I could see where the pop reports would show too many of a particular card due to re-subbing, not really sure how one could be lost from the reports though? I'm far from an expert on PSA and cert #'s but could this one (40448789) be old and therefore graded before the pop report came into existence?
