Interesting take considering it stands for Krampus which is literally a demon that punishes naughty children.

but it also helps you find out people who are actually a drag on the chain

Not very well because we can't measure the value that user brings to the chain.
So it's a completely one sided equation with question markets on the other end.

The assumption that someone with a KE ratio of 30 is a drain to the network is the exact problem I'm talking about. Anyone who works for a corporation that doesn't own stock in that corporation has a KE ratio of infinity, and yet they are not a drain on the company and are in fact generating value for it.

It's an interesting metric to throw out there on a frontend...
We'll see how it goes.
