One stroke. No undo. Find out how round you really are.
The score is the variation in your stroke's distance from its own centre, so it does not matter how big you draw — a small careful circle beats a large sloppy one. A stroke has to sweep most of the way round to count, which is why a short arc does not score 99%.
