It covers the first week in August to the first Sunday in September, which should be something like Aug 5th through Sept 2nd.
That'd allow a 5 day period for MP3 to sell. If VGC was remotely correct with a 310k first week number, it shoulda been enough to mention.
So either Pachter is dumb and won't bother projecting MP3, or the VGC numbers are vastly off - which I doubt.
Back from the dead, I'm afraid.
