M_B vs. ﹩{\rm{\Delta }}{M}_{15}(B)﹩ for our entire grid of 4500 models. The relationship of Phillips et al. (1999) is overplotted as a red box. Models with ﹩{\rm{\Delta }}{M}_{15}(B)\geqslant 1.55﹩ are definitively sub-﹩{M}_{\mathrm{ch}}﹩. Both ﹩{M}_{\mathrm{ch}}﹩, sub-﹩{M}_{\mathrm{ch}}﹩, and even some super-﹩{M}_{\mathrm{ch}}﹩ models are consistent with ﹩0.8\lt {\rm{\Delta }}{M}_{15}(B)\lt 1.55﹩.
