Why this differs from similar rows?
Same He-medium data as sibling row but excluding the six highest-pressure points (diamond-Raman-derived pressures), using ruby pressures only.

Evidence from the paper
Excluding the six highest pressures of run 3, which were determined from the diamond-Raman shift (Sun et al. 2005), yields the same EoS parameters within uncertainty: V0 = 74.697(7) Å3, KT0 = 159.5(6) GPa, and K' = 3.74(3) (using ruby pressures only).
