  By using the Krylov subspace technique to generate the spin coherent states
in kicked top model, a prototype model for studying quantum chaos, the
accessible system size for studying the Husimi functions of eigenstates can be
much larger than that reported in the literature and our previous study Phys.
Rev. E 108, 054217 (2023) [arXiv:2308.04824]. In the fully chaotic kicked top,
we find that the mean Wehrl entropy localization measure approaches the
prediction given by the Circular Unitary Ensemble. In the mixed-type case, we
identify mixed eigenstates by the overlap of the Husimi function with regular
and chaotic regions in classical compact phase space. Numerically, we show that
the fraction of mixed eigenstates scales as $j^{-\zeta}$, a power-law decay as
the system size $j$ increases, across nearly two orders of magnitude. This
provides supporting evidence for the principle of uniform semiclassical
condensation of Husimi functions and the Berry-Robnik picture in the
semiclassical limit.
