So no need to accept or discredit these numbers on blind faith. We can take a data point and relate it to the system being sampled, query it, and determine the likelihood of it being a rogue value or an accurate one. Isn't that good practice?
You know I agree with that. What I have an issue with is when faced with an odd occurrence someone proposes one of the least likely options as the explanation. Let me clarify; Brad (and this isn't directly aimed at him and I don't think there's any need to point fingers) saw a much higher than expected sales numbers and he thought:
Brad said:
There is no alternate explanation being put forth. Absent a major game release, a price drop, a new hardware revision or a major holiday, there is simply no other way to explain a huge jump from May to June [...]
My issue is the first sentence. How can there be no alternate explanation; very quickly three different and more plausible explanations were provided. Let's say this is the only explanation that comes to mind. Just as one should question one's reality and not accept the world that is presented to us so should we be just as skeptical about our own reasoning.
The brazillian thing starts out as an article post about an email Patcher sent. It's not clear from the article whether the Brazil came out of Pacher or was added from a secondary source. That alone is convoluted but assuming it's true that would mean one or several things:
a) Patcher has information that severely undermines NPDs credibility, instead of publishing an article that would garner hundreds of thousands of hits and probably a pay-rise he instead discloses this information via email to a website that is considered by many as untrustworthy.
b) NPD is knowingly compromising their standards. Next month PS3 could reach 700k if it includes shipments to Spain; things will escalate until NPD is laughed out of every gaming outlet.
c) If the NPD does not allow Sony the same rope, the NPD must be conspiring with Microsoft against Sony.
Despite there not being a shred of evidence Patcher said that or even that it's true, despite the ramifications of the information if true, according to some this is the only possible explanation.
So let's consider that is the explanation, the article in question states:
Michael Pachter did tell me in email however that much of the X360 year over year rise came from a) free X360s given away with Windows 7, and b) X360s sold directly to distributors (some of these units apparently ended up in Brazil) - and Microsoft convinced NPD to count both. Pachter didn't have figures on how many units those promotions added, but estimates that X360 would have dropped slightly year over year (-5% to -10%) without those inclusions.
Note the underlined part. The first is a promotion, the second is cheating. Jacob casually ignores the later. So, to reach those numbers, that would mean the sales between 380k and 400k. Patcher has no figures for the promotions but estimates it (how?) at around 110k.
To reiterate: we haven't seen the email, the author would be more interested in publishing himself, than to divulge that to a "competitor". If true it would mean a colossal blunder or a conspirary involving the NPD. The VGC article casually ignores cheating. Finally, the article mentions there's no figures but there are percentages, without explaining how those percentages came to be. And this is the only explanation being put forth?
