Hey, I just wanted to know how accurate is Vgchartz?

Also, off topic, but do console manufaturers ever release press releases with console numbers?

Approaching 15%+/- I believe.

And yes, they sometimes do... but they try to twist it to make it seem like they're doing better than they are.

An example would be "We have sold 50 million units around the world", when they really mean "We have sold to retailers, AKA SHIPPED, 50 million units."

+/- 15% is probably about right, they shoot for within 10% accuracy each week.

It is worth pointing out that this is the error margin for the current week only.  The error margin for the total sales is extremely small, since figures are adjusted as more and more information comes in.  I believe when we analyzed Q1 reports from Sony, we discovered accuracy of within about 1% for total PS3 sales as of the end o that quarter.

This is the important thing.

The shorter the timeframe, the greater then error. Since weekly figures are tweaked when additional information comes out (NPD, financial reports, etc..) the error in the accumulated, worldwide sales are very small (compared to other sales figures anyway).

Note there is no guarantee *any* released piece of data (i.e. even from the makers themselves) is completely correct.

US/Japan should be within 1-2% of real (accepted) results - Europe could have a higher accumulated error (but no more than 5% I would say). 

ioi said: Yes, LTD data is within a percent or two, latest weekly data should be within 10% in general if not better than that. Xbox360 >> PS3 this week btw

 America or WW?

ioi, you spoiled this weeks big surprise :(

hahaha ioi, what a spoiler :P

this website is more than accurate enough
