Placements

I was Gold 5 at 0 lp. This season i did my placements, and i won every single one of them. I didn't do bad at all, i had over 50% kill participation in every game but one, and i contributed to every game. Even with me winning EVERY SINGLE PLACEMENT, I got put in silver 5... that's lower than what i originally got 2 years ago when i barely played this game. I don't understand how that works and i think that its absolutely ridiculous. Can someone explain to me how this works. I've gotten 10x better than I was 2 years ago, I know for a fact. When I placed the first time I didnt even win every game, i won like 6 of 10... with me winning EVERY SINGLE PLACEMENT this year how the heck did I get placed in Silver 5. http://i.imgur.com/6aF0mQp.png PICTURE RELATED
