Ranking: From "Nobody" to "Master Justice"

I think there should be more clarity in what advances judges to the next level. No one I talk to understands how they achieved "Master Justice", and I would certainly like to know how myself.

I think there should be specifications on how to achieve each rank.....like whether you need to judge a certain amount of times, or if its based on fairness instead of random voting.

I also don't understand why I am in 2nd place as top world judge, but I am only at the rank of Academic?

Could someone please help me here?

Sincerely,

someone told me that in order to become Master Justice you need to do 500 judging sessions, but I found this is NOT true, because I have noted some players who are Master Justice ranked and only have 100 judging sessions
