Isotopes having the same half life's has been held without any contradicting evidence purely because if the rates changed they did it in such a improbable way that made them look unchanged.

You cannot just assume they have to fit you're own agenda without any evidence or reason to think so. | Saying that radioactive decay is not constant over time.
