Oh, I wonder if the 19k is two weeks of sales. Did Media Create release any data last week? Because Oricon for example combines two weeks of sales at the end of the year so we won't see data until next Tuesday for 12-26 through 1-08. Although I wouldn't expect the MC numbers to be out until next week if that were the case, unless it has a different weekly reporting period. And if it were two weeks of sales I certainly wouldn't expect 19k to make the charts over the holiday... hm.
What site did you get the MC number from? Maybe there's clarification there.
