Why this differs from similar rows?
Cites Ross and Hazen [1990] single-crystal XRD, K'0 fixed to 4; sibling rows cite different original studies (Fiquet et al. 1998; Mao et al. 1991).

Evidence from the paper
These results are in excellent agreement with the single crystal study of Ross and Hazen [1990] which yielded K0=254(13) GPa with K'0 fixed to 4.
