Note that the sample size was ~ 200 games for each stat so we can’t say much about the anomaly at 18k. One thing to note, though:

Conrad_Melville: Conrad_Melville: I believe komi is too large for weaker players, as they lack the ability to exploit the advantage of the first move

Isn’t it more likely that komi is irrelevant for weaker players? The game is far more likely to be decided by mistakes that cause huge swings in the score.
