The discipline you are looking for is called Statistics
It's a pretty funny sentiment.
It's also, unfortunately, reflective of how even talented individuals pass through advanced accreditation programs without locking blades with - or at least entering a general understanding of - fundamentals. Old timey British boarding schools would have called it "Logic" back in the day.
I am reminded once more of the differences in MSFS and Xplane: one uses a statistical table based model based on existing aircraft, and the other uses laminar flow analysis, fluid dynamics, and physics. One of them tells you something about unknown aircraft, and the other most definitely does not.
