Aielyn said: Jabbamk1 said: VGChartz has been known to just make numbers up. For example. VGChartz had 15,000 sales for Dynasty Warriors 8 Empires on PS4 in the USA 2 weeks before the game released because they forgot to update the delayed release date. That shows they made the number up based on a prediction model and no actual retail tracking. Therefore VGChartz can not be compared to NPD, IDG, Gfk or Media Create who base their tracking using POS data, not predicted data or made up data. Post about NPD/VGChartz

 

I understand what predictive modelling is. 

 

But basing it on zero actual POS data makes the whole thing inaccurate and a bunch of guesses. At that point it becomes wildly inaccurate. 

 

Compared to NPD who use actual POS data from retailers. 

 

Your argument about NPD is wrong as well, I understand that all numbers are going to be estimates, but to say VGChartz is anywhere near as accurate as NPD is ludicrous.  Using the whole "well all numbers are estimates" argument is pointless as that's blatently obvious. But when NPD are basing their estimate from actual data direct from retailers, are quoted by every major organisation and are seen as industry leading then what you're doing by saying they must be inaccurate makes no sense. 

I can guarantee the 90-95% number is valid. 

Do you have a source for that?

What aielyn said is true, however that doesn't mean it's not a big mistake to release numbers for an unreleased game.
