We calculate your weekly views on a rolling basis. This means that if you check your stats on a Tuesday, you'll see weekly stats for the week ending that Tuesday (in other words, the past seven days). If you check your stats the next day, you'll see your weekly stats for the week ending that Wednesday. The same goes for all the previous weeks. Because of this, you may notice small fluctuations in the weekly views, since they are calculated on a rolling basis.
