Build GGA/GGA+U/R2SCAN (Mixed) phase diagrams via new API

Papers of materials project that discuss the GGA/GGA+U phase diagrams have been well known. Well, is there any paper discussing the accuracy of GGA/GGA+U/R2SCAN mixing phase diagrams? Does the mixing operation make it superior to GGA/GGA+U phase diagrams?

Thanks!
