According to the PGA of America guidelines, "When play is in groups of four, groups will be required to play at a 4-hour and 21-minute pace for the 18-hole round. When play is in groups of three, groups will be required to play at a 4-hour and 3-minute pace for the 18-hole round. PGA Officials will use discretion concerning the Pace of Play of early groups. All groups will be expected to play at a reasonably fast pace, i.e., groups of four 14 ½ minutes per hole, groups of three 13 ½ minutes per hole."
