 In contrast , for a set of sequences exhibiting an anti-correlation between \kappa and -SCD, the simulated T^*_{\rm cr}'s are---contrary to RPA prediction---quite insensitive to \kappa or SCD . Additionally, we find that  the LLPS propensity of IDPs with a strictly alternating charge sequence might have been overestimated because stabilizing interactions among such sequences require spatial alignments that are more difficult to achieve in real space than stipulated by RPA or lattice models. Taken together, our results underscore both the utility and limitations of RPA as well as the \kappa and SCD parameters .
