Time-averaged accretion rate ﹩\overline{\dot{M}}﹩ and feedback power ﹩\overline{{\dot{E}}_{{\rm{fb}}}}﹩ for the a* = 0.9 runs with different ICs: fiducial nonrotating (black), corotating (blue), counterrotating (red), and weakly magnetized (green). For reference, the fitted relations ﹩\bar{\dot{M}}({R}_{{\rm{B}}},{a}_{* }=0.9)﹩ and ﹩\bar{{\dot{E}}_{\mathrm{fb}}}({R}_{{\rm{B}}},{a}_{* }=0.9)﹩ (Equations (7)and (8)) are shown as black lines.
