Geometry of the circle and how it applies to shot shaping .

[HungryBear]

From the above:

That being said- It would be that the golfer could strike the ball at any point on the "circles" with the same results relative to the tangent to the circle at the point struck. ??
Which then leads me to the 2 thoughts. 1. Is the circle shape important beyond practical use? 2. Is anything important beyond alignment of the clubface relative to the direct of the clubface at impact?
