It's based on your most recent stats i.e: you got the knife rank for say getting 25 revives a game, and then you play 3 games and in those 3 games you get 10 revives your rank can actually drop. You have to try to keep up your stats to keep your rank.
you have to be constantly playing the game, if u stop playing it will drop u slowly, i believe like in 1 or 2 days ur rank starts going down, its very frustrating which is why i stopped playing it, also if u tend to go down or die a lot then ur rank goes down, if u revive team mates it helps it go up faster
