Why this differs from similar rows?
K'0S fit restricted to data up to 13.3 GPa, within the hydrostatic limit of the methanol-ethanol-water medium; sibling row uses the entire data set to 20.2 GPa.

Evidence from the paper
Using only the data up to 13.3 GPa (considered to be within the hydrostatic limit of MEW), one obtains: K'0S = 3.80 ± 0.25 and μ'0S = 2.09 ± 0.15, values that are well within the uncertainties of those which were determined from the entire data set.
