Why this differs from similar rows?
Cites Boffa Ballaran et al. [2012]; fitting the data only to 25 GPa gives K_T = 236 GPa, vs. wider-range fits of same study in sibling rows (0-40, 0-75 GPa).

Evidence from the paper
it was noted that if the compression data were fitted only to 25 GPa ... then a K_T of 236 GPa was obtained. Table 2: Boffa Ballaran et al. [2012] 0-25 GPa 236 (7) 5.6 (8)
