Why this differs from similar rows?
Table I cites Ref. 10 (Yoneda), ultrasonic to 7.8 GPa under nonhydrostatic conditions (may bias K'); sibling row cites Ref. 9 to only 3 GPa.

note
Authors note these ultrasonic results were obtained under nonhydrostatic conditions, which may bias the bulk modulus pressure derivative
