well i'm not talking about a full year, but as of now if someone is judging  this years sales, he's gonna think well why did switch dominate in JAN so much, and its because of the extra week, and the only reason why switch is ahead at the moment.

Don't you realize that 2018 is 53 weeks long?

what does that have to do with anything i'm saying?
