Why this differs from similar rows?
Cites the Zha et al. (2000) primary MgO pressure scale (KT0=160.2 GPa, K'=4.03); sibling row instead cites Speziale et al. (2001), which has a different K'.

Evidence from the paper
the fitted equation of state of MgO underdetermines the pressure by 8% at 100 GPa when compared with the primary MgO pressure scale of Zha et al. (2000), with KT0 = 160.2 GPa and K' = 4.03.
