FA of the first Δm_p = 0.05 M_⊙ with respect to the average FA of the accreting material over the mass at the end of the simulation. The dots show $\frac{{\mathrm{F}\mathrm{A}}_0}{\overline{\mathrm{F}\mathrm{A}}}$ of all the 124 stars that have reached an age of at least 974 kyr. The efficiency factor of sink accretion is set to 50% to account for the mass loss via outflow. That means the stellar mass only increases by 0.025 M_⊙ for accretion of 0.05 M_⊙. Light blue corresponds to 41 stars with M_* < 0.2 M_⊙, orange to 41 stars in the range 0.2 M_⊙ ≤ M_* < 0.8 M⊙, green to 21 stars in the range 0.8 M_⊙ ≤ M_* < 1.6 M_⊙, dark-red to 7 stars in the range 1.6 M_⊙ ≤ M_* < 3 M_⊙, purple to 7 stars in the range 3 M_⊙ ≤ M_* < 5 M_⊙, brown to 2 stars in the range 5 M_⊙ ≤ M_* < 8 M_⊙, and violet to 5 stars with M_* > 8 M_⊙. The red squares correspond to the median per bin, the dark-blue horizontal lines show the mean per bin. The grey dotted line shows the mean value of all stars and the light-grey area marks the corresponding standard deviation.
