Well I think you have to adjust when the big guns talk because that is what people will go by. They have access to better data then anyone since they know what has shipped and what the demand is etc. For example NPD's numbers will be in line with those by Nintendo and MS else they will make MS and Nintendo seem like liars or people would discredit them. Since the big 3 are awlays quoting NPD it is in their best interest to be within what they are reporting. MIght be bias but that is how it is. Nothing wrong with ioi making adjustment based on the figures provided by the big 3 since they may have a larger sample then ioi.
