Thanks for your suggestion, Rikafip. Honestly, I don't make new analysis on local boards because the one I made for the thread was based on help and data dump from LoyceV, not from DdmrDdmr.
The level of activity was identified from their stats (my long ago analysis). I don't follow their changes recent months because I don't think such stats will change considerably after a few months. So let's me see later.
I will use monthly statistics in your thread for OP's coming updates. And sure, a bonus for you (I advised you doing that), when I do it I will define colors for boards to help them having consistent colors over different charts. Stay tuned! (I will update color-recoded charts here)
I changed my plan and imput data from Rikafip, then decided to use estimated merit per 100 posts rather than merit per post.
Notes:
- Total posts are new ones in April but I don't know how total merits are for all posts (includes before-April posts and in-April posts) in each local board. I guess it is for all-time posts, includes old ones.
- Boards which zero new post in April were excluded.
