How come artificialanalysis.ai ranks Gemma4 above Qwen3.6 27b in SciCode

Just came across this coding benchmark: SciCode

Artificialanalysis.ai reports a ranking which contradicts the feeling we've towards those models in real life coding.

Is Gemma 4 really that good, or a benchmarking issue?

EDIT: The contribution of this benchmark to the Intelligence index of artificialanalysis.ai:
