Same as Fig. 9 (although with the zero points set at log T_eff = 3.85), but comparing the H-burning sequences with those originally computed by Miller Bertolami (2015) under different assumptions of the evolution on the TP-AGB with the same code and microphysics. This shows the uncertainty in the computed post-AGB crossing timescales due to uncertainties in the treatment of 3DUP episodes on the TP-AGB. Miller Bertolami (2015) models show a better agreement with the results of Weiss & Ferguson (2009), which were also computed under the assumption of very efficient CBM processes on the TP-AGB.
