Chekov vas undervaited...

What do a bunch of nerds who develop powerful face-recognition technology at Carnegie Mellon do with it? Run it on all of the Star Trek original series episodes, of course! One of the results was the graph below, showing the proportional amount of screen-time of each main character in each episode.

I had no idea Kirk, Spock, and McCoy dominated the episodes what much, or that Chekov was only added in the second season, and barely had a role after that (except for a couple little blips).
