Where the pitch is, on every run
Everything measured from a video is in metres off one quadrilateral, so if that is wrong every delivery is wrong by the same amount — and the pitch map still looks perfectly reasonable, which is what makes it worth a page of its own. Each run below shows its reference frame with the four points drawn on it, so a bad one is obvious without opening it.
The automatic finder is out by 137 to 429 px on every run here, about the width of the pitch itself. It is a seed and nothing more; the four points are yours.
