# of players in game per month does not represent Subs paying for the game. Many subs do not play in a given month. A 1 sortie do nothing rank may be the lowest rank for the game but doesn't represent all of the players who have that rank. Rank tells me a lot of things about how players play the game. It generally doesn't determine skill, but you do have to have a pretty decent level of skill to be #1. I think trying for a high rank can test your general understanding of how well you are capable of performing in the MA relative to others performance.
