Why do the authors get to decide the play length description? One person's 6/8 length story is other's 4/8. Case in point, "Mattias the One Knight", by JJJ-thebanisher, and Blackwell's Diamonds, by ViolinAndDeerstalker. JJJ's story is 19,408 words long whereas Violin's story is 5,664 words long.
Since the site can count how many words there are in a story, why shouldn't it also set the story length description?
Or is that too hard to do for something not very important?
