Problem Bot Index

Thinking on this more, I actually really like the KNN idea. It's the only one that really tells you "you can and should be doing better against this bot", as opposed to "this bot might just have a weird score profile". (RamBots are the perfect/extreme example of this - they can show up as Problem Bots even if you're doing well against them.)

I know when I'm trying to figure out who I could do better against, I don't look at PBI, I compare to DrussGT. ;) I understand it would be a lot of calculations, but it should still be simple to code up, and it's all just basic math operations.
