Why this differs from similar rows?
MW sample with 78 mol% FeO (Jacobsen et al. 2002); sibling rows report 27 and 56 mol% FeO samples from the same study, with different K'.

Evidence from the paper
Jacobsen et al. (2002) measured the pressure derivative of the isothermal bulk moduli KT' by X-ray diffraction for MW with 27, 56, and 78 mol% FeO to be 5.49, 5.53, and 5.55, respectively.
