Figure 3

These 3 figures show the organizational success of the P, C, and B populations respectively, as measured by the population-wide Closeness criteria. We can see here that the 60% family levels (i.e. the Random networks) will do the best regardless of the population's affiliation preference. More importantly, we can see it pays to add family structure for any type of affiliation preference under the Closeness criteria for success.
