What's required for a bot to have KNNPBI?

I've seen many bots have KNNPBI; however my bot still have no KNNPBI (all zeros) after a long period of time ;( http://literumble.appspot.com/BotDetails?game=roborumble&name=aaa.SimpleBot%200.022d

So what's required for a bot to have KNNPBI?

Finally after having 978 pairings the KNNPBI is shown. Anyway, still wondering what made KNNPBI to be all zeros.

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

KNNPBI (and the other batched rankings, NNP, Vote) are calculated once every 8 hours, since they can't be calculated incrementally. If you remove your bot before it is calculated, it won't be calculated, since it doesn't get recalculated on old bots.
