Did those experts confirm it or just not refute it?
My emunah doesn’t come from Torah codes, and I think it’s dangerous to hang your emunah on something which may one day (and possibly already has already been) refuted.
In the other hand, I wouldn’t scoff at it either. We do have some cases where Rishonim have discovered patterns, and we do know that Gematria is a genuine chochmah. There’s no question that Hashem did put information in the Torah in hidden ways, so there’s no reason to think that any discovery made isn’t genuine, even if it doesn’t prove anything. I also think it’s equally, if not more, dangerous for someone’s emunah to scoff at it.
