Evidence from the paper
Table 1 (Zhang et al. (2021), Brillouin scattering): K_S0 = 307.5 GPa, K_S' = 4, G0 = 229.4 GPa, G' = 1, Pmax = Re-fit to 14.6, Tmax = Ambient. 'By re-fitting the data (up to 14.6 GPa) to the finite strain equations, the K0 and G0 of poly-crystal stishovite yield 307.5 and 229.4 GPa.'
