It sounds like you're saying that better mathematical models can't possibly help because our current mathematical models aren't good enough. Huh? Isn't better theory exactly the answer to "how" and "why" questions? Why would you not want to improve the theory because the theory isn't good enough? Better theory is how you explain and guide real-world experimentation. Plenty of completely intractable problems have suddenly become quite tractable with better math.
