You're missing the point again. You are looking at this under the assumption that the force applied by each model to produce tides is equal, and therefor must be in essence the same...
But it's not.
The RE Model states that the gravity of the moon is what is pulling on the large bodies of water, which causes a large tide in oceans and a very reduced tide in smaller bodies of water like a lake. This is due to the principles of gravity, which are based heavily around *mass* as I understand them. (Again, I know... I am no scientist.)
Now... with the FE model, mass should not, in any way, matter. The entire planet tilts to one side and the other, but the direction in which the planet travels and the UA maintaining that movement remain constant. That gives us the tides in your model. HOWEVER, were it to be true, there would be an equal shift in ocean levels AND lake levels. And it would expand to a free hanging body like a rope, which is hanging downward. NOT because of the rope's mass, it's not considered at all in this model because gravity doesn't exist as it does in the RE model. The concept of /down/ changes.
