There is a moderate/strong correlation between an event’s Dwyer Score and the number of comments in the event’s Reddit MMA live discussion post.
I used this metric (comments in r/MMA’s live discussion post) as I felt it was a consistent value to measure event interest that was immune to the natural fluctuations of TV viewing figures. It’s also a value that can be used to measure PPV, Fight Pass and free TV events alike.
