How does the classification of control centers work?

Can someone explain to me how the ranking of dispatch centers works? We make a daily effort to keep our dispatch center at the highest realistic status, we have sufficient vehicles, POIs, operation keywords and ratings. Despite this, we are ranked lower than e.g. this “fictional” dispatch center with fewer POIs, vehicles, ratings and fewer active players.
