Could have been, yes.... likely... no.
The error margin determines where it could go up or down to if things don't go as expected (say a store that VGC gets data from sells proportionally less than usual)
NPD themselves it is possible for them to be 10% out (and in the past I am pretty sure they have been, thing is we don't get to see any adjustments NPD might make) though I would guess it is rare for them to be more than 5% out in their monthly numbers.
VGC going by month are probably within 10% each month.... but it is still more likely that the numbers fall nearer the middle of an estimate (by VGC or NPD) than near the edge.
For something to be likely over a million (likely meaning more chance of it being over than under 1 million) the VGC number would have to be over 1 million.
