December is a 5 week NPD month. (November 30 - January 3) Given that, all of his initial predictions seem way low when compared to VGC data.

 

 :O Okay

Well, VGC in that time-frame (missing 1 week)

Wii: 4M (so ~ 5M total? That would mean Pachter is 2M lower...)

X360: 2.1M (so 2.5M total? Would mean Pachter being 1.2M lower....)

Ps3: 0.9M (so 1.2M total? That would mean Pacher being 500K lower...)

 

I think you've got the wrong weeks.

 

It could coorespond to these4 weeks, plus next week.

VGChartz Hardware data for the period 06th Dec 2008 to 27th Dec 2008:

Console	Wii	PS3	X360
America	3,162,172	740,675	1,611,184

In any case, Pachter looks it be low for all 3, based on VGC data.

 

 erm, that is all of NA divide it by 1.1 for so to get US.

I think- (which is just as good as a patcher prediction..lol)

Wii- 3.5 in US alone

360- 1.8 mil in Us

PS3- 800k in US

Dividing by 1.1 is NOT the same as multiplying by 0.9

I repeat, it's NOT the same.

When you get so close to 1 it's kinda not a huge deal, I admit, but it still gives you faulty numbers.

Dividing by 1.1 is more the same as multiplying with 0.91

Multiplying by 0.9 is the same as dividing by 1.1111111.....

It's a common mistake that can really, really mess up your calculations.

 

For reference, try multiplying by 0.5 and dividing by 1.5. You do not get at all the same answers.

 

um... I hate to tell you this, but.. the US % of NA is not EXACTLY 90%, it is 90% give or take 1 or 2 % points depending on the Week.

so dividing it will not give you a faulty number, just it will not give you the same number as mult. by .9

I just tend to like division more for some reason, people can dow whatever they want.
