9.10 Official Time
The following rules dictate the use of timing devices during IPSC matches. This includes any rules regarding arbitration based on crediting timings of a course of fire.
9.10.1 Official Timing Device
Only the timing device operated by a Range Officer must be used to record the official elapsed time of a competitor’s attempt at a course of fire. If a Range Officer assigned to a course of fire (or a more senior Match Official) deems that a timing device is faulty, a competitor whose attempt cannot be credited with an accurate time will be required to reshoot the course of fire.
9.10.2 Unrealistic Time
If, in the opinion of an Arbitration Committee, the time credited to a competitor for a course of fire is deemed to be unrealistic, the competitor will be required to reshoot the course of fire (see Rule 9.7.4).
