Table 1. Comparison of average remaining standard deviations of ΔV of the cations in the reference sets of cation environments for the three investigated parameter sets.

Parameter set	Cut-off	ΔV	ΔV (n > 20)†
softBV	Self-consistent	0.0719	0.0807
softNC1	First coordination shell	0.0797	0.0891
convBV	First coordination shell	0.1157	0.1146

^†Average standard deviation when considering only those cation–anion pairs for which the reference set comprised more than 20 cation environments.
