You can distill judging procedures down all you want. You still run into the problem regarding the judge's assessment of what is considered "confusion".
At a recent competition, someone was judging a 4 year old competitor. When it was evident that the 4 year old didn't know the proper starting procedure, rather than try to explain it to her, the judge started the timer for her after she had picked up the cube.
At another competition, a judge tried to call a competitor up for his solve. When the competitor didn't show up, the judge wrote DNS for that solve and returned the (still scrambled and covered) cube to the scrambling table.
In neither of these incidents did the judge think to notify the delegate before or after taking action. The judge wasn't a non-cuber family member either, which goes to show that just being a cuber isn't enough to qualify you to be a good judge.
It's easy enough to say "oh, just enforce regulation 1e2", but many competitors are first timers or young children who barely know the competing procedures, much less how to judge, and the incidents outlined above go to show that competitions have gotten big enough that organizers can't just pull competitors indiscriminately and be able to trust their judgment. If you as a competitor consider yourself an experienced judge, actually go up to volunteer. Don't just wait for the organizer (who probably is already juggling too many tasks) to enlist you.
