I guess I'm sorting hijacking the topic, but this situation is not a problem in the GBA. A random number app is used to assign box #s to tables. A separate sort is run for each of the three categories. Judges take seats randomly except spouses, significant others & close friends may not sit at the same table. After the first round, judges leave the judging area & the tables are reset. When called back in for the second category, judges again take seats randomly but may not sit with the same group from the first round. Comments?
