If something is showing a pattern of accuracy shouldnt we consider it plausible. I mean be sceptical and continue to check it for accuracy. But going back months/years to find 1 or 2 things, perhaps inaccurate, doesnt mean the entire site is inaccurate. If you have to dig that it should tell you hey this actually isnt that bad.
I mean if a few inaccuracies is all it takes what the hell does that say about this chart. Didnt ioi say something like a 10% margin of error is considered acceptable? |
A 10% margin of error in exact numbers when projecting sales.
Here we're talking about a basic top 10 list, with no numbers... where a 10% margin of error still wouldn't fix times when they got it wrong even if you assume Amazon got it wrong by the smallest amount possible. (Which is an assumption.)
Considering that Amazon doesn't give exact numbers, the actual amount they've gotten wrong vs NPD is no doubt higher.
That it got a few months "right" with NPD when Amazon doesn't have any exact numbers is nothing more then confirmation bias, as the ratio between PS4 and Xbone could be WAY different then on NPD.
.It's also noteable that this is a time where NPD actually gave numbers for Hardware and software officially

So you can't realy hide the software numbers as accurate by using the groupings.
For example, on Amazon Super Mario Brothers Wii > COD 360
Despite NPD Having 360 outselling NSMB Wii by more then double.
Also, Wii being above it... etc.
Clearly Amazon moved a LOT less COD (Both kinds) then other retail stores.
In that list the software isn't remotely in order.
