So, between Europe and Japan VGC have:
Wii - ~155K undertracked.
360 - ~168K undertracked.
3DS - ~222K undertracked.
DS - ~383K undertracked.
PS3 - ~386K undertracked.
PSP - ~531K undertracked.
So, it looks like the DS, PS3, and especially the PSP are all undertracked by a significant amount. Not sure if it is really enough to warrant more adjustments, but it may be. As for the US, we don't know the exact percentage VGC uses from Americas to represent the US. So the US could be pretty accurate.
