I'm pretty sure the "4" comes from mapping the letter grades A, B, C, D, F. "A" has the most points (4) and "F" the least (0). Most of the time -- but not always -- the letter grades have already been mapped from a numerical scale or percentage, e.g., A=[90-100], B=[80-89], C=[70-79], D=[varies?], F=[can't fudge a D].

I've even heard it more-broadly stated that there are NO long-term stable lunar orbits. It's an issue for orbital debris: since (1) objects don't burn up on entry, and (2) an uncontrolled orbit is impossible to predict in the long term, therefor all lunar orbiters should be removed rather than abandoned and lunar deorbits should be targeted rather than random.
