Why this differs from similar rows?
Cites Tarrida and Richet [1989] K0=275 GPa (DAC, no medium), one of three literature comparison values quoted; sibling row instead cites Tamai and Yagi [1989].

Evidence from the paper
"This range of K_T0 value is significantly smaller than the previous values of 275(15) [Tarrida and Richet, 1989], 281(4) [Mao et al., 1989], and 325(20) GPa [Tamai and Yagi, 1989]."
