Honestly, I don't really know AutoGluon, if this does xgboost tuning that's good.
I do still think ELO scores are still a way to obscure results though. For all we know this is like 0.1% better than a "normal" approach on like 70% of tasks and a tire fire on others.

Definitely feels like they're hiding the ball lol.
If they had good benchmarks they'd talk about them.
Not comparing to tuned xgboost is also a warning sign.
