I don't think it really matters, since you are talking about a variance of less than about6 feet.

If flying at 150 meters out, I suspect most judges will not be able to determine the 60 degree top line within 20 feet. You're watching the plane and somewhat lose the point of reference to the ground to judge 60 degrees. Since the debate is less than 6 feet its a non issue.

For down grading going above the 60 degree line, I don't recall ever taking points away for it. I would assumethe manueverwould have to be really tall.Most likelywould be caused byflying ittoo close (toward the flight line)and would also cost additional points as its nearly impossible to stay in the 60 degree sides as well.
