Are you an indigenous aboriginal native person? Then you will likely make very limited eye contact. There's nothing at all unusual in this. It's cultural.
As for my personal Aspie eye contact percentage "guesstimates":
If you are intimate with and trust someone, you might expect to make eye contact about half the time.
If you don't know someone and don't feel comfortable with them, you may make very fleeting and peripheral eye contact (glances).
I suppose research exists regarding "eye contact percentages", but I believe this is a more individual and personal choice. Just because someone gets kudos for producing a load of scholarly research does not mean they are correct. For all the academic community knows, this person could be an Aspie or HFA person with great compensation strategies.
I've known Aspies who seem to stare holes into others. I've known Aspies who are very self-conscious regards making eye contact and rarely look into anyone else's eyes. I tend to fall into the latter category. When I'm at ease with someone, maybe I make eye contact 20 - 25% of the time. When I don't like someone, I make no eye contact with them at all. I make a great deal of eye contact with my cats.
