Cross-WLF viscosity model coefficients for the virtual material in which either the RSS (Equation (3)) or the WRSS (Equation (15)) was used as the minimization function. For both fits, the following fixed parameters were selected ${\mathrm{D}}_2=413.15 \mathrm{K}$, ${\mathrm{A}}_3=51.6 \mathrm{K}$, and ${\mathrm{D}}_3=0 \mathrm{K}/\mathrm{Pa}$ (the original parameters upon which the simulations were based are given in Table 3).

Original	${1.0 \times 10}^8$	${1.0 \times 10}^5$	0.40	17.44
RSS fit	${4.34 \times 10}^8$	${1.15 \times 10}^5$	0.37	19.41
WRSS fit	${2.40 \times 10}^8$	${1.04 \times 10}^5$	0.40	18.59
