I think there is something wrong . You counted all posts from Saturday (even if it’s just a few) for the past week which ended Friday. Basically you chose a wrong cutoff date for the total posts.
Will the new week start today ( Sunday ) or still yesterday?

Campaign week: Saturday to Friday UTC.
It's not that hard to understand. Look at the spreadsheet. Saturday's posts got included in the last week while they should count for this week.

But whatever, I make more than 40 posts anyway.
