Jesus Christ we (the real warriors of this game) have explained this many times in different threads.
Explaining the wrong information in different threads is a great way to misinform the playerbase.

When a player or mob attacks a player, the chance is a base 5% plus 0.04% per rating difference.
When a player or other mob attacks a mob, the change in miss chance is 0.2% per rating difference if that rating difference is 11 or more. If the rating difference is 10 or less then the change in miss chance is 0.1% per point.
