The cumulative residence time T( > e) as a fraction of the total integration time T_tot, versus ﹩{\mathrm{log}}_{10}(1-e)﹩, for the BBH–SMBH system of Figures 2–3, run 50 times with the random initial outer mean anomaly M₂ ∈ [0, 2π). Red and blue colors correspond to SRFs (in this case GR precession) being switched on and off, respectively. The solid lines show the median SA results, and the shaded bands show their 5%–95% range. Dashed lines show the DA results; they asymptote toward zero when they reach their predicted maximum eccentricities ﹩{e}_{{\rm{\max }}}^{{\rm{DA}}}﹩ (vertical dotted lines).
