What's required for a bot to have KNNPBI?
And in 0.022b the KNNPBI is still all zeros, see http://literumble.appspot.com/BotDetails?game=roborumble&name=aaa.SimpleBot%200.022b
You should have more pairings but I don't know how does it decide.
The computation of those values are batched, they are computed every 24 hours. One possible explanation for the older version to be still all zeroes is that maybe only the latest version of a bot is considered when doing the computation? Not sure about this, though. Just makes sense, had a really superficial look at the code. You can probably try to figure it out here: https://bitbucket.org/jkflying/literumble/src/38f6e71de1c6?at=default
