I'm not even going to get into the entire NSS calculation because it's been beaten to death and will continue to be until.... well until there are no longer naval aviators (god forbid). I heard a "rumor" that the box labeled "Score" on an Aviation Tracking Summary represented your position respective to the top of the bell curve for that evolution. I.e. 1 is average, more than 1 is better than average and less than 1 is.... well, you get the idea. Is there any truth to this? There are all sorts of numbers on those things, but quite frankly it is Greek to me. After a through post flight beating, it would be slightly comforting to know that I'm still above the average.
