Hi @Maria0
welcome to the club of indignated victims of statisticians gone crazy. Please shout out to @Jonny and @Marjo0 to make your voice heard.
As for last information, there is a "well thought" program behind the scenes which will count all your activity. Everyone starts with 1, even senior staff, and then raises in grade with every posting or getting liked or whatever, possibly in relation to number of overall posters.
We don't know how high you may raise, in my bubbleshooter I went up to 19 before getting bored.
When you stop posting, you fall back down. That's the same in the bubble shooter, get killed and start all over. As this is boring, they recently offered me to buy entrance levels - we are not at that point yet here but maybe that's a future business idea ?
(This remark is cynism, not a proposition)
