Dependence of maintaining the MMR chain among the three innermost super-Jupiter planets as a function of the ratios ${\tau }_{a,e}^{+}/{\tau }_{a,d}^{+}$ and ${\tau }_{a,d}^{+}/{\tau }_{a,c}^{+}$. The plot exhibits a grid composed of 20 × 40 simulations. The color scale represents the standard deviation normalized to the minimum value of the resonant angle λ_e – 2λ_d – λ_c + 2λ_b over 20 Myr of evolution. Thus, values close to 0 indicate that the MMR is preserved throughout the entire evolutionary period. Here, ${\tau }_{a,c}^{+}$ and T_d are fixed at 1 and 2.75 Myr, respectively, while ${\tau }_{a,e}^{+}$ and ${\tau }_{a,d}^{+}$ are varied. The green and black crosses represent the values that correspond to the fiducial model and the simulation in Panel (C) of Figure 4.
