how? do they just take the average of all the predictions? |
How it works is that GAF opens an NPD prediction thread and people guess how many units each platform sold that month. A few weeks later, the OP will release the rankings based on how close people's predictions are to the real thing. This was how we got a general idea of how much the PS4 and XB1 sold in February NPD.
