> It's not engineering if you're just guessing as to what is degrading the performance and what might improve it.
Engineering is literally the art of making educated guesses and then testing/proving/disproving/improving upon them. Nothing is exact. Everything is approximate. Iterate until the result is good enough.
This is false. A bridge is not built with approximations, it is built with a deep understanding of structural physics. Yes there are some unknowns, no it's not "educated guesses".
