Pips for rank 1?

Why is it that I can win 5 games in a row as a survivor, staying at rank 1, but I lose 1 and drop to rank 2? It’s impossible to tell who is rank 1 after you win the game as a killer. Was it a survivor who is usually a rank 2? Or a rank 1 you just beat? It’s hard to know. If i make it to rank 1, it should be somewhat easier to stay at rank 1 than losing 1 game. There should be 5 pips for rank 1. If you max on pips you don’t move anymore. If you lose a game, you simply go down to 4 pips but still rank 1. If you keep losing, you’ll fall to rank 2. Anyone agree or have a better idea?
