The charts seem off this week

[melon]

I know BioShock was over 800,000 last week, but now it got bumped down to 733,000....am i just not seeing something? or am i wrong, and the charts are accurate and consistent?

and also, last week, i remember The Orange Box (360) selling more then Halo 3 (in its 2nd week), and that week has changed now (check it out).

someone please clarify.

thanks.
