In a previous paper \cite{Jahn:2018dke} we presented a methodology for computing the topological susceptibility of QCD at temperatures where it is small and standard methods fail. Here we improve on this methodology by removing two barriers to the reweighting method's moving between topological sectors. We present high-statistics, continuum-extrapolated results for the susceptibility of pure-glue QCD up to 7Tc. We show that the susceptibility varies with temperature as T−6.7±0.3 between T=2.5Tc and T=7Tc, in good agreement with expectations based on the dilute instanton gas approximation.
