20. Twenty Teams

If you are simply running a 20-team tournament, without having to worry about teams qualifying to the next level, you have all kinds of flexibility. An easy format is simply four pools of five. The top two of each pool advance to a quarterfinal single-elimination, and the bottom two of each pool advance to a "Division II" quarterfinal single-elimination. (This 16-team Division I & II elimination is shown in Section 16.1.) This way everyone gets lots of games. What follows is a sample format you can use: 
                            20-team format
    
                    Rnd   Odd      Even

                    12    quarterfinals
                     2      semifinals
                     4        finals
    
                    Pool A: Fields 1 & 2
                    Pool B: Fields 3 & 4
                    Pool C: Fields 5 & 6
                    Pool D: Fields 7 & 8
For 20-game schedule: All games to 15/cap 17. Games should be capped at 20 minutes before the next round. If a game runs into the cap, the next game is scheduled for 20 minutes after the preceeding game ends, and is capped at 1:40 past the new scheduled start time.
