US and NA Wii sales are 1:1 with Wii Sports, regardless of any type of bundle purchased. Only Japan has no game included. So, looking at the picture below....
Wii sales in NA = 137,733
Wii Sales in All (less Japan) = 130,272
A + B = 268,005
Wii Sports sales = 247,605 ?
Given that this week Wii Sports sold 2,865 units in Japan, shouldn't it actually be 270,870 world wide?
Not to mention, if I use this weekly chart, I have no clue how you came to the 247,605 number in the first place as my summation of that last week on that chart equals 223,121. If anything, this just shows you have innaccuracies in how your DB and/our queries are formed.
I love this site, but man this type of stuff provides so much food for the fodder.
EDIT: Ignore struck out part. ioi gave reason below. :)
