The tournament mode is under-specified. Write down the current tournament mode and add it to the rulebook.

Here is my proposal for the Tournament mode. Please make your comment.

Round-Robin phase.
The first stage is a group phase and will be played as a round-robin. The teams will receive the true points they scored during the competition. The points will be accumulated in this phase and the teams will be ranked according to the accumulated points in descending order. Depending on this order, only the first 80% (number will be always rounded up to an even number of teams) teams are qualified for the Playoffs.

Playoffs:
Qualified teams will be divided into two groups. The first team in the ranking of the Round-Robin phase will be placed in the first group and the second one in the second group. Then the third one in the first group and the fourth one in the second group, etc. Then all teams in each group play against each other. In case that there are less than 7 teams qualified for the Playoffs then all qualified teams will play in one group. At the playoff stage, the scoring scheme will be different. As each team in this phase directly competes with an opposing team, a ranking score will be determined as follows. In each game, the winning team gets 3 ranking points, the loosing team gets 0. A team wins if it achieves more points in the game than the other team (cf. Sections 5.5 and 5.6). In the case of a non-zero draw, see section 6.1.1 for overtime. If, after overtime, a draw is not resolved, both teams get 1 ranking point. If both team end with a zero score, each team gets 0 ranking points. Points awarded for commentary are not considered in this decision. The ranking in each group is determined by the ranking score of teams, highest first. If two teams have the same score, the overall total in-game points are summarized and the team with more game points ranks higher. If there still is a draw, the direct comparison of the games of the two teams is used to break the tie. If this still is unsuccessful, a coin toss determines the higher ranked team.

Finals.
The best teams of the two groups ( or the first two teams in case of one group) of the playoff phase will advance to the grand finale. The second ones of the two groups (or the third and fourth team in case of one group) will compete in the small finale for the third place. The team that scores more points after the regular game time wins. If there is no winner after the regular time, refer to section 6.1.1. If after this there is still no winner, a coin toss will decide.

The detailed seeding will be created at the event and can be adjusted to meet time requirement.

It should be ensured, that there is always an even number of teams to have equal group sizes. Maybe the bracket can be changed to: number will always be rounded to an even number of teams.

I agree with the comment of Florian and will change it in my proposal.
