The "top reviewers today" list at https://stackoverflow.com/review/suggested-edits/stats seems unnecessary. It's essentially a bunch of 20's with a couple of moderators at the top.
Does this list serve some other purpose?
Generally, top lists are used to motivate people through healthy competition. Since the majority of users here are capped at 20, this doesn't really accomplish that goal. Also since the number of people who end up with 20 (and fairly early on in a day) is so much greater than the number of people that can be displayed on this list, it's essentially just a random list of users.
I'm not sure it should be there, it seems extraneous.
