The Booking Grid:
The horizontal axis shows Forest, Pines, & Beeches, which are "loops" of nine holes each.
The vertical axis shows eight minute time slots, representing teeing-off times. The maximum number of balls that may tee off in an eight minute slot is four. Parties comprised of more than four player are allotted more than one slot. The system calculates the requisite number of slots, though this may be overridden by the opeator.
In this example, Alexander Beetle has a party of 3, teeing off at 08:24 on the Pines loop, and continuing with their 10th hole on the Beeches at 10:24. There are 17 players in Henry Beedlebower's party, requiring 5 slots; his party may choose to tee off in two groups of four players, and three of three players.
