Precise measurements of weak processes are incredibly powerful in testing the structure of the Standard Model of Particle Physics. This is true of processes satisfying a (weighted) combination of conditions: 1) suppression of the SM background, 2) precise experimental measurements, and 3) no specific NP suppression (otherwise called "Good Luck"). In this talk I will discuss the topic in general, argue that we are mostly out of #3, and focus on some of the hard work that is needed to overcome the problems that arise as a result.
