How to Determine if Timing Apps are Manual or FAT: Per NFHS interpretation, for any system to be considered fully automated timing, the system must be started automatically at the triggering of the gun. A person manually starting or stopping the app or the system being started by the sound of the gun is still considered manual timing.
