Theymos has not adjusted the source merit allocations in a long time, and has not appeared to have adjusted merit sources in a long time, even as merit sources have become inactive.
That is why I feel like he may reallocate the merit distribution since there is no changes were made in that area for very long time and also as you said some merit sources becomes inactive needs to be filled with new merit sources or reallocations or certain boards and sections will ran out of merits for sure no matter how good those posts are.
That doesn't make any sense.
IMO a reallocation is probably necessary, but I don't think it will happen. My assumption is that merit sources with large allocations probably don't exhaust their source sMerit, and merit sources such as TMAN will have their source merit allocation always be full. This will probably lead to metrics reflecting that there is sufficient source merit.
