I'm not sure how it's calculated exactly, but it seems to be quite strongly effected by game shape.
I imagine it has something to do with player efficiency, similar to Hollinger's PER stat.
While the first part of your answer is correct, the 2nd part is absolutely false. The rating has absolutley nothing (or at least very little) to do with a player's efficiency in that particular game.
While much of how it's calculated is secret, game shape, stamina/minutes played, player attributes and that players ability to effectively play at the position you played him all strongly effect the number.
