The TBN and TAN are equal which isn't really ideal, but I agree you should try a slightly longer interval and see if that causes TAN > TBN. Do you do a lot of short trips? What's your driving style?
I would consider this a good report and the start of a reassuring trend. The next report should be very telling.

Not that many short trips, minimum 10-15 mins when I drive. I sometimes go to store to store after that, does that matter? Most of my driving is on the weekend, I would take it to above 6-7k RPM occasionally like on freeway merges. I do autocross events as well, maybe once a month to two months in this car. I do plan to do the RB's at the next change, or should I try pushing it a little longer?
