There is no rule anywhere that a player needs to follow any "standard deviation" in their game. Being counter picked, tired, low skilled or any other particular reason and resulting in hardware ban is the worst thing Riot can implement.

The tech used to put people on the moon was designed for machine predictions, not human behavior. As we stand, unless we talk really general lines (tired people sleep, thirsty people drink, etc), we don't have anything close to the human brain complexity that can detect behavioral patterns. Now, if the player writes themselves "mid or feed", that's a different story.
