Assuming it works as in the past...
(from the site)
There are currently ten leagues in total. The Premier league, league A, league B1, league B2, league C1, league C2, league C3, league D1, league D2, and league D3. Three are demoted from the Premier league, and three from league A promoted. Three are demoted from league A into leagues B1 and B2. The three best players from B1 and B2 are promoted. To rank the players, the position in the league is considered first, and then the number of points and SCs won are used to distinguish between players who were in the same position in different leagues. That means that the two Champions and the better second place finisher will be promoted. The worst six finishers in B1 and B2 (i.e. the last three in each league) are demoted, and the best six in C-level leagues are promoted (i.e. the champions and the runners-up). Nine players are demoted from C-level leagues, and so nine are promoted from the D-level.
