Final 182W excess as a function of impactor mass and impact time, for an initially reduced value of Hf/W = 0.69 that may represent the inner Solar System composition (Nimmo & Kleine 2007). The lower amount of 182Hf makes it easier for the impactor core material to transport excess 182W to the combined post-giant-impact core. Hence the pebble accretion time-scale of 5 million years is here consistent with core-mantle equilibration factors as low as feq = 0.5 (left plot) and feq = 0.25 (right plot).
