When we originally had the "box" there was no definitive way of exactly saying who had broken the box.
Back in the day when the 75 degree markers were in the rules, there was a definitive way to tell if the box had been violated. It's been interesting to observe ever since. Carry on!
Back in those "days", with the 75° markers, the pilots were flying MUCH further out so that they would not break the 75° "line".....As a result of that, the footprint was extremely LARGE & many contests were in jeopardy of losing the flying fields for future contests. The rolling circles or any Y axis maneuvers could not be judged as breaking the "box" since there was no way (unless boundary judges were instituted) to tell. A judge could say that the box was broken, but there was no way that it could be proven.
