Fragment formation efficiency vs. sink formation efficiency. The color code accounts for the different initial conditions of the realizations, as described in Fig. 5. Specifically, the crosses and the points mark the M500 and M1000 realizations, respectively. Shaded areas illustrate the range in FFE recovered across the three projections, indicating the uncertainty in the distribution. The diagonal dashed line marks the equality between fragment formation efficiency and sink formation efficiency. Data points are expected to lay above the line. Only if the sink particles were resolved, the fragment formation efficiency could align with the one measured for the sinks.
