Are we talking about the same point system? 1 point = 1 positive trust rating you got?
No.
Each person gets N points whenever they are trusted by someone, and loses N points whenever they are distrusted by someone, where N = 0 if the rater is less than a full member and N = [rater's activity]/120 if the rater is at least a full member.
"Trust" here means "added to someone's trust list", not "received a positive trust rating".
