6.25 = x

6th round:
There will be 11 winners - 11 players for the next round and 11 games
7th round:
There will be 5 winners plus one player which sits - 6 players for the next round and 5 games
8th round:

9th round:
There will be 1 winner plus one player which sits - 2 players for the next round and 1 game
