I have been tracking my tiers lately as an experiment. Last night I played 25 games. 24 games I was the lower tier. I played on all tiers from 2 through 8, I was top tier on 1 tier 5 game. I'm sure their MM has a matrix for placing one in game. Only thing I am not sure off is how WR is factored in. Although I will not throw matches, I wonder how poor performance in a battle would affect tier position. Not a whine post, I 've been curious about this and trying to approach this scientifically.
