you gain efficiency for earing career points, you gain efficiency for using them, and you earn extra points for using them on a promotion (i.e. using them more efficiently by earning more later). so when you promote, you earn MORE points, so you get even MORE efficiency.

so, in essence, no, your efficiency score does not affect your ability and gameplay, it simply a score for how well you're doing in your career

ok?
