In fact Rol, to argument my theory why the numbers can be correct, I want to say that those numbers from VGC are from a different set of days. If those 5 days instead of 400k like you said are 300K, for example, then there's 650k units sold in that period being 250k-300k the rest of the month which can be probable too.
Because we don't know which days were better for Switch last year...., (if 5 days prior BF or after), we can not assume anything. If what i'm saying is correct, then every number given by Nintendo is correct.
But that's just my theory...
