Why this differs from similar rows?
Table cites Boffa Ballaran et al. [2012]; K_T = 251 GPa regardless of 10 or 75 GPa fit range. Other rows cite different original studies (Ross and Hazen 1990; Fiquet 2000; Vanpeteghem 2006).

Evidence from the paper
Boffa Ballaran et al. [2012] also determine K_T of Mg-Pv to be 251 GPa regardless of whether the compression data were fitted only to 10 GPa or to 75 GPa. Table 2: Boffa Ballaran et al. [2012] 251 (2) 4.11 (7)
