Why this differs from similar rows?
Cites Speziale et al. (2001) polycrystalline He-medium result (KT0 fixed 160.2 GPa, K'=3.99); sibling row instead cites the Zha et al. (2000) primary MgO scale.

Evidence from the paper
For comparison with Speziale et al. (2001), who fixed KT0 = 160.2 GPa ... The resulting K' is significantly lower than the reported Speziale et al. (2001) value of K' = 3.99(1).
