I'm pretty sure you need to lower VGC by 10%, not raise NPD by 10%.

Lowering VGC 10%:

Console	Wii	PS3	X360	PSP	DS
VGC Americas	3,519,970	1,540,622	1,474,565	1,512,619	3,265,832
NPD (US Only)	3,482,000	1,608,000	1,354,000	1,482,000	3,187,000
Percent Difference	1.09%	-4.19%	8.90%	2.07%	2.47%

Off by 2.07% on average.

It doesn't make much of a difference, it depends on whether "the rest" is meant to be 10% of USA or 10% of the whole Americas. I assumed ioi meant it was of USA.

Even then it is just a vague number to help work it out, I wish he would split it into "USA", "Canada" and "other Americas" (the last one would be mostly Mexico I think, allthough Brazil must be a decent enough market)

 

Well ioi is always telling people that to get the US only its roughly 90% of VGC numbers. It really does make a difference in the final percentages for each console and it still makes a big difference in the average, by my calculation the average is 50% different if you do it the wrong way.

As much as it is intended as a rough indicator this type of stuff is still cause for a lot of bashing on VGC so I'd still rather see it done right.

I agree though splitting it would be nice, but its hard to say what that would involve..not too mention he would have to go back and split it retroactively.
