With your controversy classes, if more than 75% of the votes are either 2, or 3 or 4, he will have a low controversy.
If 50%-75% of his votes are either 2, or 3 or 4, he will have a medium controversy.
If 15%-50% of his votes are either 2, or 3 or 4, he will have a high controversy.
And if less than 15% of his votes are either 2, or 3 or 4, he will have a very high controversy.

i am really sorry, but need more explain.

you said if some user average is 3.2 , what if another value ?
