Let's thank Shun (the webmaster of cjwfc.com) who gathered these data for us. From my understanding if the rating (in Taiwan) is over 1%, that means it's very good already. Not sure about how the rating was calculated, it seems quite different from the result of ratings in Korea and Japan. They must base on different statistical methods. However, if we look at the ranking, STH did a great job. I believe it will have higher and higher ratings.
