A timing point defines the location at which times will be recorded, all raw timing data from your timing systems will be assigned to a timing point. 

For simple races with a shared start and finish line only a single timing point is required, for complex events with multiple timing locations then you may need to create additional timing points. 

The recommended naming convention for timing points is to name them in upper case and identify the physical location or distance of the timing point rather than a generic name.
