  Recently we estimated that about 5 percent of supermassive black hole triple
systems are fundamentally unpredictable. These gargantuan chaotic systems are
able to exponentially magnify Planck length perturbations to astronomical
scales within their interaction timescale. These results were obtained in the
zero angular momentum limit, which we naively expected to be the most chaotic.
Here, we generalise to triple systems with arbitrary angular momenta by
systematically varying the initial virial ratio. We find the surprising result
that increasing the angular momentum enhances the chaotic properties of
triples. This is not only explained by the longer life times, allowing for a
prolonged exponential growth, but also the maximum Lyapunov exponent itself
increases. For the ensemble of initially virialised triple systems, we conclude
that the percentage of unpredictable supermassive black hole triples increases
to about 30 percent. A further increase up to about 50 percent is reached when
considering triples on smaller astrophysical scales. Fundamental
unpredictability is thus a generic feature of chaotic, self-gravitating triple
populations.
