 #### Note on model consistency
 
-The readability scores produced by this python package tend to differ slightly from the scores produced on the official [jreadability website](https://jreadability.net/sys/en). This is likely due to the version difference in UniDic between these two implementations as this package uses UniDic 2.1.2 while theirs uses UniDic 2.2.0. This issue will hopefully be resolved in the future.
