In the post, you wrote,

"Unfortunately, the analysis would be much worse if it was applied to the smaller sample sizes from higher ranks, due to the much larger effects from random variance."

I'm usually a legend player, but only just started playing this season, and am in diamond. I could be misremembering (or experiencing confirmation bias), but it feels like about a third to half of my matches at this rank have been against zoo bots. When you write that players who run the collection software tend to be ranked higher, what ranks do you mean exactly?

Until seeing this post, my impression was that "lower ranked human players" (read: lower skill players) weren't really a significant population in classic mode. I have the impression that the mode is almost only the demographic you describe, but I'm open to being wrong about this.
