Assuming that the T'bird works as you stated, you might still want to know where in that sawtooth the supposedly "fixed" error falls. Maybe this is unimportant if all you want is a stable reference frequency source, or very important if you actually want to know what time it is. However, the always somewhat noisy phase lock means that the "fixed" error is not constant, merely less variable than otherwise. What I don't know is whether or not the hardware can even be aware of this variability- I kind of suspect not.
