This is a very effective way to show this data, and really highlights some of the issues well.

The only ray of sunshine I would add is that we have not at any stage had a sustained period where the rate of user growth has been increasing, so comparing the last 3 months is measuring against a period where there was a large upsurge in users. We may just now be back to more regular levels of user growth.

This does beg the question why haven't we had sustained growth in the rate of new users?
