Final spin periods of our model asteroids plotted against the fraction of mass shed in each of the 195 S‐, B‐, and M‐class outcomes. Starting spin periods are P = 4–12 hr and P = ∞ (i.e., no spin). Note that three S‐class and one M‐class events have final spin periods between 10 and 20 hr (i.e., beyond our P = 10 hr plotting limit). Regardless of the starting spin period, most disruptions spin up the model asteroid to P < 6 hr.
