-Are all merit sources have same smerit generation?
I don't think so base on my understanding, every merit source has his own monthly allocation rate which may differ from each other, if am right.
-Another question is once a merit source can be a lifetime merit source? Or is it also pick and drop system like DT¹
member election?
I don't think its a lifetime source, but as long as the source keep to the ethics for the fare distribution of the smerits received, there wont be issue on that, also, i perceived of recent, we have a drop in number of the merit sources by one, and we still have an additional member who got confirmed to be a merit source as well, nothing is permanent in life.
