Your posts should show up more quickly now; the first five posts typically are detained longer in moderation.
The 19s you have would have the potential to impact the FSIQ, CPI, EFI (Expanded Fluid), QRI, and AWMI (Auditory Working Memory). There are insufficient subtests to calculate the EFI, and the other subtest in each of QRI and AWMI is not close enough to 19 to make using the ExNorms likely to be additionally informative. And, as you note, only DS changes at all on the ExNorms, which means only FSIQ, CPI and AWMI could be affected. The latter two indices are not ones that are usually prioritized in analysis of GT profiles, since they both have to do with efficiency skills, rather than reasoning (although there is evidence that strong WMI of any kind is correlated with math ability). And one additional sum-of-scaled-scores point on the FSIQ is not going to change your life.
And to your side note: the NSI is another timed task, with significant impact from the non-motor contributors to processing speed, and aligns best with your KTEA scores in Reading Fluency and Letter Naming Facility. It measures mostly something called rapid naming, which is one of the three principal neuropsychological underpinnings of learning to read (along with phonemic awareness -- curiously, one of your lowest scores on the 2017 achievement testing (labeled "phonological processing"), at "only" 109 -- and phonological memory/auditory working memory, in which you consistently demonstrate significant strength, also in the upper 130s to 140s). I'm a little surprised it was administered, since you had already demonstrated that you had a substantial store of language, and it would have been easy enough to quickly check for reading fluency prior to giving the NSI. It's usually used for investigating reading challenges in elementary-school students.
