$A_2^{+}$ Parameter evolution for all GCs as a function of time (a) and number of relaxation times (b). All models follow a similar evolutionary path as the two populations spatially mix. The panel a scatter reduces when we trace the cluster dynamical ages. After one relaxation time, the initial difference between the r_h ratio of 20 (N2M, N1M, N1M-ra, N05M, and N05M-wf) and r_h ratio of 10 models (N2M-r10 and N1M-r10) is indistinguishable.
