One of the main challenges with the CR metric as currently defined is the fact that it includes Ru, whose loading varies across the samples, possibly skewing the results. To address this, an "adjusted" CR can be calculated, to focus on different subset of metals, excluding Ru in the HeACS and HoACS sums. Such adjusted CR allow for example to interrogate the degree of mixing between Pt and Pd in the series of alloys which have the same Pd and Pt loading but different compositional complexity (Ru-Pt-Pd, Ru-Pt-Pd-Ir and the two HEA samples). The results and statistical significance of these adjusted CRs are detailed in the Section S5.4 of the Supplementary Information. A consistent trend is observed, showing an increase in CR value with the number of components, which mirrors the trend observed with the original CR.
