Scoring tennis using finite-state automata

For some reason, the scoring system for tennis is very strange. Fortunately, the convoluted logic is easy to express as a finite-state automaton (FSA).

Hire talented people and get out of their way?

Today's quote is: "In most cases being a good boss means hiring talented people and then getting out of their way."
