Mute I think it's fair to review the translation speed, however I don't think it should influence the rating of the story. That should be based on the content itself. Like someone else said, you can get an idea of the content from a few chapters, especially if those chapters are hardy. So reviewing a story based on a few chapters should be fair enough, short stories even more so.
Although... are there any short stories on here? I've looked at a few that were complete, they were always in the hundreds of pages in length.
