Weird rumble scores

I’m experiencing similar thing. Score is constantly dropping as more battles come.

But is’s not hard to explain.

1. For bots you get 100%, when getting more battles, it’s either changing to 100% or less than 100%, and the more battles the higher probability it gets less than 100%, so score can only decrease as more battles come.

2. For bots saving data, it’s only getting better the more data they have.

Since this affected a lot of bots, affecting 0.1~0.2 APS is quite common.

Worth mention that 1 APS decrease in 10 bots is enough to give you -0.1 APS.

Btw, 1 season is generally not enough to get stable results. For reliable result, 50000 or even 100000 battles are needed. Anyway comparing after ~30000 battles is generally acceptable.

2 would explain a bit of a score decrease, although not that many bots save data. I don't think 1 is true; sure some 100%s will become 99.5%s but also some 99%s will move up to 99.5%. Without 2, the APS estimated from a small number of battles should be an unbiased estimate of the true APS. And it takes 1 APS decrease in 100 bots to get -0.1 APS since there are ~1000 bots in the rumble!
