Why this differs from similar rows?
Text-stated combined value (K0=256, K'=3.9) derived from several data sets [Mao 1991; Wang 1994; Funamori 1996; Fiquet 2000], distinct from the single-source Table 1 value.

Evidence from the paper
Text: 'the bulk modulus (KT = 247 GPa) is underestimated with respect to the experimental value (256 GPa with K'T = 3.9) derived from information contained in several data sets [Mao et al., 1991; Wang et al., 1994; Funamori et al., 1996; Fiquet et al., 2000]'.
