The cumulative nonclassicality of the quasi-probability distribution (QPD) behind the out-of-time-ordered correlator (OTOC) exhibits different time scales that have been conjectured to be useful for distinguishing integrable and nonintegrable Hamiltonians (arXiv: 1806.09637). We further investigate the QPD for a quantum kicked top, and use the time scales of its nonclassicality to understand the relationship between entanglement and chaos for different parameter regimes.
