Just play a lot of games
you are paried with random group from your current league
who wins the most games promotes
lets say I play 1000 blitz games and win 0, draw 100 and lose 900 then i get 100 * 3 points
You play 30 blitz games and win all, then you get 30 * 9 points so you end up with 270points
You might be orders of magnitude better than me, but if i play more, i am more likely to promote
