I don't think that anyone was meaning to imply that kids with balanced profiles who are high in VCI and PRI as well as WMI and PSI are not gifted but simply high achievers. I've just, personally, seen some kids who are not high on VCI or PRI, but are on the other two and who do seem to lack that depth of thought or abstract thinking ability yet they do achieve highly b/c they memorize well and process fast. They can, thus, spit back the information they just read, for instance, but if you ask them to analyze it they don't go far.
