My idea is to assess the level of activity in the local boards.
So, the first idea to determine how lively the “local boards ecosystem is”, would be to calculate the ratio between the number of posts in the local boards, as a whole, to the number of posts in the forum.
The second indicator would be the same ratio, but considering merits. So it would be merits in all the local boards over the merits across the whole forum.
Hope this clarifies.
Ah, now I get it. Not a bad idea (and something I would like to see too) but goal of this topic is to compare local boards and not to compare how they perform against the forum in general. As I said before, I wanted to to keep this overview brief and its already kinda too big so I am not so inclined to add even more charts. But I will definitely think about it and maybe include it in one of the future overviews.
I think he is finally back today, there is still hope for us

Yeah I saw, our local forum is not the same without him being all over the place.
