Both. The methodology is terrible and highly inaccurate. As someone who has taken biostatistics, ioi's way of sampling is poor. NPD samples over 50% of the sales while ioi doesn't even come close to sampling 50%. Because he uses such a small sample size, the margin of error is very high, as proven whenever the NPD results come out. I find the US sales to be highly suspicious because the XOne, for some odd reason, stays constant after Titanfall is long gone and after the price tag went back up to $500. Meanwhile, the PS4 just randomly dropped. What's worse is that even after the NPD results are released, VGC does not properly adjust its numbers.

Month after month, the PS4 is undertracked while the XOne has been overtracked with the exception of February where it was horrendously undertracked. Just wild inconsistency everywhere...
