Ah okay, that makes more sense. (I'm terrible at math)

You are correct Marcio.... it can go both ways... it's just you stated "VGC is 25% off".
This means you are assuming NPD is the more likely correct figure.... so you should use that to divide by.

To be honest I am not sure if I trust NPD though... after all ioi does get very accurate numbers for Japan (Famitsu and Media Create both track about 60% directly... and they can be off by 20% from each other easily... ioi is generally in the middle)
And in GfK regions, most of the time now when we see figures VGC numbers are spot on, and GfK tracks 90%+ in their markets.
NPD meanwhile, tracks ~60% like Famitsu or Media Create, yet the differences to VGC are sometimes quite large, so I suspect something is wrong there.... especially suspicious with VGC being too high when Sony's report came out, so if VGC was correct in Japan and PAL, it must have been America it was too high, and yet NPD has PS3 higher much of the time (last time VGC was higher for PS3 was April)
Perhaps it is true that we only get the crud figures from NPD (the freebies) in that when they realise past numbers need changing they just add it on to the next month instead.
