schedule games every 1.5 hours. Be precise and have the games start on time and end every game in one hour. teams need to arrive 15mins before the game that gives the teams that just played 15 mins to exit the field and the new teams 15 mins to warmup and get ready.
use only 3 fields in a pod. that means if each team has 15 players that's only 90 people in that area for that time being.
