Bang on, the Pacific is not 250 miles deep…

“Smoother and rounder than a bowling ball” is my usual comparison

I think that would be too much. A bowling ball is really smooth. It would not roll as well with such deviations all over the place.
At a diameter of 22 cm, the roughness would have to be in the order of 0.3 mm, which would not just be visible due to the distorted reflections, it would even be audible while rolling.

To put in perspective how shallow a 0.15% change is, a dimple on a golf ball is roughly 4 times deeper than that (0.60% of a difference in depth).
