On the user profile for favourite series, show the average series rating of that user instead of only the first volume

Description of your request or bug report:

When you favourite a series (e.g. 五等分の花嫁 (series) | L25), it will show up on your profile under e.g. “username’s favorite manga” with the rating for the first volume:


In this case, I rated the first volume 4/5 stars, but since it improved starting from the next volume, my average rating is 4.67/5 stars. Marking something as a favourite manga series but then showing a 4/5 below it feels a bit weird to me. I think replacing that with my average rating would better represent how I feel about the series.

Totally agree, and could possibly be done along with Show average score for series in list.
