Average Rating Given higher than 10

Could someone please check the calculation of the "Average Rating Given", while ranking the members by the average given rating I was surprised to see that the highest was 11 and some more are 10.01, 10.02, 10.1.
9 members have a given rating higher than 10.

This is not a bug.

Sorry but I dont see how you can get an average of 11 if you cannot give ratings higher than 10.
THis should be  a calculation bug

You are correct.
