Why this differs from similar rows?

Reanalysis of Dewaele et al. (2013) P-V data with pressures recalculated using the self-consistent scales of Fei et al. (2007) and Dewaele et al. (2004); differs from that study's originally published values and from the Richet et al. (1988) reanalysis (sibling row).
