Can someone explain the jump between these two consecutive readings? It doesn't match any known event.
Despina Baggins Roger that.
See the other chart.
Can you split Q4 out?

Is the other chart built from the same extract?
Checks out.
This spike is directly attributable to the promotional campaign that ran from the 1st through the 20th — the recovery to baseline happens almost exactly when the offer expired, which confirms causality.
Thanks , that resolves it.
That holds up.
Needs a legend.
