There was outlier in GNOME outperforming KDE by a large amount too.

Edit: Okay, maybe not that large. I agree with you, that the outlier they had (included twice even) has a huge impact. But it is some real game and with real settings and configuration. So making an exempt just because you don’t like the results would be faking the result. They just should have included a result without the outlier, just for comparison.
