We consider the dynamics of complex rational maps on $\widehat{\mathbb{C}}$ . We prove that, after reducing their orbits to a fixed number of positive values representing the Fubini–Study distances between finitely many initial elements of the orbit and the origin, ergodic properties of the rational map are preserved.
