Temporal evolution (20 Myr) of the mass of the most massive surviving body in the system. It shows the time it takes to grow an Earth-mass planet for each system (where the solid lines representing each simulation meet the dashed line). The simulations are grouped by their initial disk mass (IDM), indicated by the same color. Bodies in the systems starting with the initial disk mass 5 M_⊕ never reach 1 M_⊕ and are therefore not included in the plot.
