I'm not sure how it measures anything, but I do notice that my MMR does not get punished much for losses. If I lose a bunch of *solo queue* games in a row, my MMR might start changing a bit, but it usually jumps right back up after a few wins in a row.
At best, I would believe that it keeps track of two different MMRs for each player - solo and not solo. I kind of like knowing that when I lose with my bad friends that I'll still be recognized as a good player by the system. Furthermore, plenty of pubs love to look up enemies mid game and laugh at their win rate, information like this proves that win rate is a largely irrelevant if not an altogether pointless indicator of skill.
