Why this differs from similar rows?
Text cites a range (232-236 GPa) from more recent studies (Wang et al. 1996; Shim et al. 2000a), also cubic-cell analysis; sibling row cites older, higher-value studies.

Evidence from the paper
which is lower than the values of earlier measurements (281–325 GPa) ... but higher than more recent values (232–236 GPa) [Wang et al., 1996; Shim et al., 2000a]

note
range spanning multiple cited studies, not a single fitted value; all previous measurements were analyzed based on a cubic unit cell
