The official Matchmaking blog post

I actually tested this new revolutionary match making system as a solo q. Purposefully didnt get a single kill for two days. Almost 40-50 matches of BR both ranked and pubs. Did some dmg in the fights but stopped shooting (got assist by fault not sure if it counts). Obviously no wins with few accidental top5 (whole lobby landed in one place with 7 teams alive after first ring. Our jumpmaster landed elsewhere so we just went around looting). According to the matchmaking post I shouldve noticed a change after 5-10 matches but I didnt.
Level varied from medium sweat to uber sweat.

There is no such thing as SBMM or its being exploited like there is no tomorrow. Or perhaps the EA SBMM algorithm has evaluated me as a masochist that will keep playing as long as the situation stands.
