Actually, you didn't compare anything.

A _physicist_ might have compared the Earth and
melon alone, against the Earth, melon and Moon, that
would have been a comparison.

"Falling" is relative acceleration.

Speed, or change in speed, of approach is "falling",
this is relativity.
Experiments should be done in a way that the
existence of a "field" is not crucial to the results.

The early gravimeter measurements used pendulum
clocks, the newer ones drop triangles and measure a
change in speed of "approach" of the triangle to the
bottom of the box, which is supported by the surface
of Earth.

Change in speed of approach is the only thing
that can be measured, and it is the only thing known
about gravity. Gravity does change speed of approach,
or change in speed of approach between two objects.

Accelerometer readings do not conform to the
concepts of Newtonian gravitation or Newtonian mechanics.
