But they should be offset. Monthly MAU departures shouldn’t reflect in half-year until 5 months later. And half-year departures shouldn’t influence the MAU at all.
The fact that they line up to they day strikes me as very suspicious.

A statistician explain to me why these graphs seem correlated beyond general trend? They both seem to have localized events on the same day, but given their different timescales that doesn’t seem like it should be possible.
I raised the same concern on the other post too, but idk enough about statistics to for sure say something seems fishy.
