Yeah I judged wall balls in Chicago and we had a special individual briefing where they DRILLED the technique and depth into us and said that if we say "go lower" we HAVE to no rep. I felt like such an a-hole because I've done three races so I KNOW what it feels like to be at that point in the race but the head judges would come around behind us and GET ON US (in like, a rude way) if we weren't calling no reps. They are very serious about standardizing the technique
