It's no less analytical than using a jillion-foot circumference jig,
it just makes an elipsis rather than a circle (which, at this size, I
doubt the human eye could detect). Both methods are equally

Very easily, the ends of the arc are very different: the elipsis will
come down perpendicular to the original board edge, while the circle
will be almost parallel.
