I'm not surprised he's good at math, given his FRI and WMI, which are generally the best predictors of math achievement. In his case, the effect would probably be more focused on the face reading, and maybe, eventually, in geometry (but maybe not, since his fluid reasoning is so strong, and his spatial abilities aren't really weak, just relatively so).

And the NVI is of course quite strong, but we are really speaking of relative weaknesses here, not absolute ones. (And remember that two of the contributing subtest scores are the 19s from FR.) His NVI is also ten points lower than his VCI (which may well be an underestimate), and may be even more discrepant from the Extended VCI.

You do not need to do any additional testing to compute the extended index scores, if the examiner followed standardized administration procedures. All you need is the raw scores from the five subtests that reached max scaled scores. And the norm tables, of course, but your evaluator has those (they're also freely downloadable from the publisher's website, but I'd recommend having a qualified person doublecheck the conversions, and whether the recalculated scores are meaningfully different).

It's a lot harder to reach automaticity in handwriting than in typing. Wider range of complex fine motor skills. And a lot of extra initiations and placements, for every word when using cursive, and for every letter when using manuscript. That can be tough for learners with relative weaknesses in visual spatial skills, automaticity (represented here potentially by the relative weakness in PSI), organization or some combination thereof. Fortunately, it really doesn't matter much anymore, in the real world. Type away!

Just a bit of caution, any physician or mental health professional "can" diagnose autism, but shouldn't without specializing in it. There are so many overlapping conditions/variables, OCD, child abuse/neglect, giftedness, ADHD to give a few. A similar example, as a mental health professional, I cannot tell you how many parents come to me saying that the school has said their kids have ADHD, when it is something completely different (most often intellectual capability that doesn't match what school teaches to). The school is not qualified or trained to push that, if you are concerned, I would ask your physician for a referral to a specialist.
Some things I would look for is how do they seem to engage with people that they can connect to (which may or may not be their classmates), eye contact, early childhood development, repetitive behaviors, etc. There are so many similarities between giftedness and autism, it's important to rule those similarities out.

My therapist is convinced I have Asperger's but he may not be as well versed in giftedness. What I have seems to look a lot like MG/HG + HSP + Enneagram 5 + INTP.

By the way, I took an emotional IQ test and did very well -- except that often I can't figure out what's going on in real time when I'm overwhelmed by a conversation.

Judging from this it looks like I'm a HG AS adult now who had adapted to and learned to overcome many of the symptoms shown as prevalent in gifted AS children.

I suspect HG and AS is a very rare combination. I've met other people in the spectrum and they don't seem as well rounded as I am emotionally and spiritually. Those may be the gifted traits.

I wish there was information on gifted AS adults! It's all children...

Because the forums are largely geared toward helping parents navigate the system and advocate for having the needs of their gifted children met, most of the posts and resources will be focused on children. However, with patience and repeated online searches, information geared toward adults may be found. For the benefit of future readers of these forums, it may be helpful to post adult ASD articles in the adult forum.

There's this doctoral dissertation from a couple of years ago, that does a few case studies on GT/ASD college students, and also has a nice review of the 2e literature, with an eye especially to ASD:
