Projected final rank Ki in the unchanged world (A) and the inverted worlds (B and C) as a function of market rank at the end of the set-up period. The initial and projected final ranks were highly correlated in the unchanged world (r = 0.84), but had a very weak relation in the inverted worlds (r = 0.16 in both worlds). The vertical banding in the figures is caused by the large number of songs that had the same market rank at the end of the set-up period (see Table 2).
