When you raise or lower the elevator, the trim tab moves variably with
the angle of the elevator.

Not on the single engine Cessna aircraft it doesn't. With the possible
exception of the Cardinal which has a stabilator.

Actually, if you look closely, the trim tab does move as the elevator moves,
even on the non-stabilator Cessnas. It's not a very large deflection, and
whether it does or not isn't really relevant to this thread anyway, but it
does move.

The movement of the Cardinal's trim tab is much more pronounced, I certainly
will grant.
