You are running a contest with judged submissions. Each submission is evaluated by three judges. Judges evaluate submissions using a rubric with several factors. You need to average the judges scores and then rank the list of submissions by their average scores. You are also too lazy to deal with it.
Rankmatic to the rescue!!
Given example.csv:
email,funny,friendly,cool

bar@example.com,22,20,40
bar@example.com,30,40,90
baz@example.com,7,8,9
baz@example.com,1,2,3
