This is how i think it works. The ammount of points you get, has nothing to do with the average vote count of a user (the avg. vote points / total vote count could influence when you appear on the front, but it doesn't influence the points you receive).
When you create a post you automaticly upvote it, this upvote doesn't count for your profile score, if anyone else upvotes you, you get 1 profile point. If anyone downvotes you, you get -1 profile point.
Someone with > 500 profile score can downvote you.
Edit: The one downvoting me, could you elaborate what isn't good about my answer?
