JDax3 - your name reminds me of Jadzia Dax on Star Trek! Anyhow, there is a number you can calculate called General Abilities Index (GAI) which is a subset of the indices...it uses only the VCI and PRI and excludes WMI and PSI. From my reading, it seems low WMI/PRI does impact performance. Kids who are really high in all 4 are just out there. But lower WMI/PRI should not be used as a basis for saying a DC is not gifted.
