Abstract: A computer system utilizing a local area network and multiple computers used in association with a trapshooting competition of the type wherein each entrant in each event is, at one of multiple squad-assignment stations, assigned to a squad (of particular entrants) scheduled for shooting at a specific time and place. This system's operators, software, and hardware efficiently manage the competition, including computer-assisting assignment of each entrant to a position in a squad. The computer system has a method for temporarily restricting access to an entrant list for a squad of an event to a particular computer workstation, enabling efficient assigning of an additional entrant to a temporarily-restricted entrant list, as well as handling functions like handicapping, scoring, fees, prizes, etc.
