We've all speculated about whether longer stories get you higher ratings. Now I've got experimental evidence.
I've been consolidating several series into single, multi-chapter stories. Before the last series came down, I recorded the scores. The scores for the six single stories ranged from 5.88 to 6.33 with a mean of 6.125. The "new," 6-chapter story is currently rated 6.97.
It's not because the readers get more words for their download limit, because one chapter still counts as one download. They just prefer multi-chapter stories.
