As the title suggests, I’d like to know how accurate the PSP software sales are on this site. If they aren’t accurate, where should they be sitting at?

As accurate as the software sales for every other console are

 

 

Well we only have others data (weekly) for PSP since September 8th 2007.  So that is 2 years of no SW data.
