The Pluto/Neptune anomaly of the Titius-Bode progression is predicted in the Initial Mass Displacements of the Solar System.

Although the total Ceres mass includes an asteroid belt (2.8 AU), the total Pluto mass is unique.

Excluding Neptune, a variety of objects (Kuiper Belt) between 48.8 AU and 28.8 AU had a total mass of 10 Earth Masses (i.e., Pluto Initial Mass).
