Absolutely right!

Also, if the CG moves slowly back in flight the plane becomes a little more sensitive, which isn't such a bad thing, as by then, the initial shock of getting used to it has died away a bit!

Also, landing becomes a little easier, or slower, as the plane floats a little more when the fuel has gone.
