The numbers are clearly wrong for switch in Japan for the week ending 30th December. For the week 25-31 December in Japan the switch sold 134,519 units in Japan and you have the number at 13,000? Lol.
If you include the correct figure which is 134,519 instead of 13,683 it gives a total of 442,621 by your estimates. This is of course assuming you haven't just put in the wrong number for Japan.Last edited by JSG87 - on 25 January 2018
