We are, but what happens often with older games is that a total number with be put in place for the area, with Weeks 1 - 10 saying N/A.
For example, Sonic Rivals (http://www.vgchartz.com/games/game.php?id=2110®ion=All) has 380k others sales, but it doesn't have weekly breakdown, meaning it never entered the weekly charts at any point, and doesn't affect the tie ratio.
So lots of PSP games don't have current tracking and don't make the charts, but still have some data.
