Question 014: Judging

I have a question regarding testings. I was recently a judge at a testing. I having only judged at few testing. A judge who was senor to me to told me to increase the grade I gave student by one level. I'm a very fair and non bias judge who give students get my undivided attention when I am scoring so this did not seem to be a proper thing to do. Also, at testings, and tournaments for that matter, I notice judges on cell phones and looking off into space, not really paying attention to the students being judged. I often wonder how judges even arrive at their grades.
