Reasonable said:
All of the numbers, I believe, are based on the site getting a small subset of data (by polling and other techniques) and then extrapolating from that. External numbers then serve to help confirm the results and "tune" the algortihm. The worst region for the site to extrapolate is EMEAA so this is where there is the greatest margin of error. With the 360 being more US centric by a fair way I always assume the 360 numbers are more accueate. PS3 and Wii I take with a bigger pinch of salt because a bigger chunk of their sales is outside US and therefore more vulnerable to error. |
You are talking about HW numbers which already are pretty accurate because we keep getting official updates on it. But Software numbers are far from being accurate.
