Beginner question, why is it hard(not possible) to calculate the gain without actually building a reactor?

Surely if you have a non-satisfactory yield you shouldn't be building it. And that should be possible to estimate before we spend billions on it?

Simulations and estimations about processes in the physical world always leave room for surprises when one is doing things that haven't been done before.
