The problem with that is each element must be defined. If there is no pause to show the element completed, then there is no realistic way to judge accuracy of the element. Coming from a standpoint of judging full-scale aerobatics, there is generally a pause, but not a long line drawn. I think the powers-that-be have it wrong in FAI currently, but that's just my opinion.

That doesn't even begin to address the silliness of trying to judge a 120 degree point.
