@SuperSletsen None of us know for certain the best we can do is make guesses based on our in game experiences. I don't know if they'll ever tell us directly because once players know how it works they look for ways to manipulate it.
Based on what I have seen and heard from other players, SBMM is based on a fairly short sampling of your game stats, something in the neighborhood of the last 25-30 games played. It seems to take about that many to go from top tier lobbies down to noob lobbies. How ever in my experience it only takes a handful of really good games in a row to start being bumped up into higher skill lobbies. I had a streak of 5--6 games doing 1500-2k damage and was in a lobby with 6-7 pred squads and nothing but diamond trials coming out the ship.
It also seems to be based on an average of your teams overall numbers. When I play with my high skill friends we end up in lobbies that seem to be some place between top tier and middle skill. They occasionally have predators, some master trails coming out the ship. If I'm having a good night or week we end up in the top tier lobbies.
How ever even when I'm doing extremely well, if I play with a noob we don't seem to be in the really really hard lobbies.
