Placement games.

So, I just finished my first ever placement games, and i went 6L and 4W, mostly playing Warwick. And I somehow still got placed in Silver V, is that the lowest there is for placement games? (Unless you lose all placement games.) I also got honored in a few of the games I won, so I was wondering if that affected placement. I was unranked the entirity of last season, just learning about the game and the champions, so I would really like it if someone were to clear this up for me. Thanks in advance!
