BOF rules wrote:4.5.4 The Organiser needs to ensure that the check for these items is located such, that if they are mandatory, the competitor can easily return to obtain the required item. A further check may be required to ensure that competitors have not disposed of the items en-route to the start.
4.5.5 If such items are made mandatory then it is essential to check every competitor en-route to or at the start.
It would be a shame to have to void the JK because the organisers didn't follow some overspecified regulation...
