It sounds like you and lukeprog are doing a lot of the same things, and have the same skills... the difference is that you managed to attain these skills without needing to study them so much. On the opposite end of the spectrum, I'm sure there are people who might work as hard as lukeprog, and still not attain the results in dating that either you or him achieve, because they are starting off as more unattractive and socially impaired, or they don't learn quickly.

I know fashion well enough to turn heads when I walk down the street

If you're turning heads, then you are either great at fashion, or you are more attractive than a "7" (at least, to a sufficient proportion of women).

I can somehow build rapport with almost anyone I particularly care about building rapport with

For some people, it takes work to attain this skill.

my hair looks great when I bother to get it cut which is really a rather simple procedure

Not everyone has hair that looks great with minimal work, and some people have to spend time and effort learning how to maintain it.

Back when I was in the game I was banging cheerful sweet intelligent 17yo models like it was no big deal. I pulled that off despite the fact that I have a lot of weird psychological/neurological stuff going on that makes many people think I'm autistic or something, and I'm at only like 7 on the physical attractiveness scale.

Based on what I know of you so far, I suspect that you are substantially above the mean in attractiveness to women (or at least, to a certain subset of women). It sounds like you've developed a lot of the prerequisites without needing to try very hard. While I will congratulate you, I'm not sure that your experience suggests that lukeprog's skill development was not necessary. He just needed to work harder to put together a similar amount of skills and attractiveness. Due to a different biology and social experience, it takes different people different amounts of work to attain the same skills.

I've seen a photograph of you and you are strikingly handsome. And if you talk anything like the way you write, you give the impression of having a high opinion of yourself.

That's my explanation right there.
