I don't think it requires any box definitions, The criteria is fly your sequence so the judges can easily see it. In doing this it shrinks the box. If the judge can easily see your manuevers then you would score high. If a judge has to squint, lean out of his chair, because the manuever is being flown so it is hard to judge then they would recieve a lower score.

If you offset your center manuevers because of the sun, so that you and the judges can see them better, would this give you a higher score. The criteria states "fly the figures to be optimally judged".

good points

keep the discussion comming
