As last season i would like to get some insight into placements and its results. The previous surveys results can be found here:Just to explain how placements work and what I want to know by doing this:During placements the system tries to get to know your MMR in order to put you in the division and rank with others at your level of play.As a starting point it needs use a base value for your MMR. This is either your hero league MMR from the previous season or (if less then 15 games played in hero league) your MMR from either unranked or quick match.The result of your placements modify this value based on the results of your games with higher uncertainty then normal games to allow better adaption.By this survey I want to see how big the impact of the placement matches really is.The hotslogs MMR is in here just as additional information to see if it does relate to the real blizzard MMR at all and it is the best guess of MMR currently available.
