Changing number of forum hits

[dave1904]

Hi,

I have noticed that the number of hits changes, for example for individual visitors in the last week or the last month. Here are two screenshots that were taken within 24 hours. As you can see last week shows 4k less users than one day before. Can anyone explain this?

It's a rolling window, and a high-traffic day is no longer included.

Consider this sequence

M   T  W  T  F  S  S  M
10 [50 11 10 13 10 18 10]

The next day, that 50 on Tuesday goes out of range, so the sum will decrease even with the same number of days

M  T   W  T  F  S  S  M  T
10 50 [11 10 13 10 18 10 12]
