I feel you're misunderstanding something. That's not "this exact experiment". Matharena is testing publicly available models against the IMO problem set. OpenAI was announcing the results of a new, unpublished model, on that problems set.
It is totally fair to discount OpenAI's statement until we have way more details about their setup, and maybe even until there is some level of public access to the model. But you're doing something very different: implying that their results are fraudulent and (incorrectly) using the Matharena results as your proof.
