1, two months, and can only be played at school, so you can only play at school for 40 days in two months, five days a week. Considering the rain, it is estimated that you have 30 days of competition time, so I arranged a 3 1 competition system.
2. When time permits, playing as many games as possible will help the champion team to do its best, so we should arrange group matches.
The competition system is arranged as follows: 16 teams are divided into 4 groups, with 4 teams in each group, and single round robin is adopted. So the group match is 24 games. The top two teams in each group ***8 teams enter the knockout stage. The elimination stage adopts the single-game elimination system, with 4 games left in 8 games, 2 games left in 4 games and the last game. Together, it is 24+4+2+ 1=3 1. The European Cup and the Asian Cup are all like this.
If you feel that time is not safe, you can only let the first place in each group participate in the knockout round, so 27 games will be enough.
