Loving this tool, thank you for creating it. Also I voted for your witness.
The new report view, you might want to change the "first year" to measure the first 365 days instead of the calendar year. On mine it shows less posts in the first year than in the first 6 months.
Fantastic find. Clearly explained. I will put it on my list of things to fix, and it will go right to the very top.
In my new vision, the years aren't tied to the calendar, but the user's first post date.
