Because it's not something OP or anyone can actually measure their coworkers for, so it isn't actually a metric, just a way of degrading their coworkers. To me, it says more (negatively) about OP, than it does about their coworkers.

It reads as OP didn't indexed anything and just wanted to denigrate people around him to try to portray himself as some kind of ubermensch towering over his peers.
