Does anyone know how NPD handles months? Does it do it by weeks like vgchartz or does it calculate each day individually?
If it calculates by weeks, how many weeks does it use for December?
Sorry if this has been answered before, I am just curious as to how NPD could relate to VGChartz data.
Edit: Kind of answering my question a little bit here is a tweet I found, but maybe someone has more specific details?
