A suggestion. Any organisation intending to hold such an event must hold a trial meeting well ahead of the main event. using the exact same targets (as near as makes no difference) in the same terrain. Also to use whatever the "rules" require be they chronos or FAC equipment.
Check list stuff.
There shouldn't be such unforeseens. Problems happen (deer munching through strings...) and whistles are blown but it should not result in major stoppages.
