Scott,
The full strength of the gravity-inducing radiation extends about 50 miles downwards in Cater's scheme, but it doesn't stop at the point. The influence of the gravity-inducing radiation continues but diminishes after that depth is reached. Anyway, the same phenomenon which you are here describing could occur in relation to a point along the gravity-inducing " diminishing continuum," shall we say. Why not?
Again, your scheme of gravity has to explain a few other phenomena which don't correspond well to the idea of gravity as caused by the density of mass.

For all objects like the ocean waters situated on the Earth'ssurface, it is only
the degree by which they differentiate from the barrycenter that provides
any tendency
to "react" to the Sun gravitationally. The Earth Moon system orbits the
Sun in an
eccentric orbit. This means that at any point in time, the portions of
the Earth's surface
that are closer to the Sun than the barrycenter are prone to sheering
forces in that direction.
They are a matter of no more than a thousand miles or so closer to the
sun than the
perfect balance point which is the barrycenter.
