We teach Rally but it is a steep learning curve for class and trainers at the moment! The scoring system in my opinion is quite complicated and you really have to be in full thinking mode when following someone round a course! Think it is easier to take part rather than judge! But I am going on a workshop, probably same place, in August to learn to be a proper rally judge and things will hopefully become much clearer LOL! My ‘bible’ is Click Your Way to Rally Obedience by Pamela Dennison.
