Let's suppose that VGChartz had 2000 retailers in the US, and NPD had 5 times as many, at 10000, just for the sake of argument. Then rather than a 95% confidence margin of error of 2.2%, it's now just under 1%. In other words, while "more accurate", it's not exceptionally accurate. And you have "no doubt" that NPD has "way more resources"... but you have no evidence, and no reasoning to justify the claim... at least, none that you have provided to us. So here's your challenge - provide solid evidence that NPD has more resources than VGChartz with regards to video game sales data collection. |
If first parties didn't think that NPD was the most accurate source of data for NA, they wouldn't be quoting the numbers everytime NPD releases their report. I wish someone had a collection of the comparisons of NPD vs VGChartz numbers. VGC's purpose is to fill the gap for system wars for when official numbers are not available. I still recall the sensationalist "DS becomes best selling system of all time".
