To maintain as much consistency as possible in comparing all the curves and tables and to avoid excessive computation, we have calculated and reported all performance metrics for values of y = 1, 1.1, 1.2,…. This results in adequately smooth and sampled curves except in one case. For the SPRm curve of ED-PRE in Fig. 5, finer sampling led to a significant increase in SPRm, from 53 at y = 1.2 and 1.3 to 60 at y = 1.26. This additional point is included in the plot in Fig. 5. We also checked the maxima of other SPR and SPRm performance curves, using finer sampling increments. However, since the change in appearance is minimal and the maximum values of the curves would change by no more than a few tenths, these additional findings are omitted.
