Growth is according to an increase in the number of accounts. And actually dropped in overall percentage of users. I did the calculation for it, but was unsure if I should include it. Now that someone has asked I know I should have.

I personally don't think it's premature, a lot of growth lines up with his arrival. All growth? No, and I should phrase it better, but we can definitely attribute some to him. Everything is difficult to confirm, but we can rationalize and use evidence to say one way or another.
