One or both of the two people who beat you had far lower numerical rankings than you and took more points from you than you gained from the people you beat - who were probably also ranked lower numerically, losing fewer points to you.
This is most often seen when you're one of the only A/B drivers in a Race A lobby with C/D drivers.
Did you check immediately after the P3 finish or after your disconnect in the next race? Any race you DNF will treat your DR like you finished DFL. My guess is the DR drop you're seeing is because of the DNF.
Thanks for your response. I now remember canceling an entry and that would have me dead last. That explains the loss of points. I really appreciate both of you helping me and showing me a new way to follow my points.
