I didn't realize you were using the WISC-V table - sorry there!
I was under the impression that the extended norms would have been released by now given the timeframe mentioned by Pearson (see bottom of this post). I may actually end up consulting with DD's educational psychologist once the extended norms are released. If they do push her FSIQ upwards in any significant way (a big 'if,' I know), I would possibly be willing to see if she could participate in research on the subject.
Q: When will extended norms be available for the WISC�V?A: Extended norms are used by practitioners who are evaluating intellectually gifted children, to inform interpretation. Extended norms must be validated with a sample of children who are highly intellectually gifted, and that case collection takes some time because these children are rare. The validation sample is currently being collected. The WISC�V was released at the beginning of December, 2014, and the extended norms are planned for release approximately a year and a half after the initial release of the WISC�V. (source:
