Getting a Feel for player oppenions on MMR To skill Grind.

How many games do you think it takes till match maker has a good grasp on your skill? I want to take a moment to say this is a rule of thumb, as LOL is constantly changing and players are evolving and improving at all times, Skill is difficult to properly measure and should be shifting. MMR also will shift a bit as well even when there's no decrease or gain in a player skill. A dedicated OTP getting a buff or nerf does not necessary increase the players skill but would impact their MMR. So what I am looking for is not 100% accuracy as that's not achievable but a good estimate that's consistence once reached.

As is the new trend in my posts, an appeal to any one who participates. Please, do not down vote others for disagreements, do so for low quality (upvoting some one else for agreement is fine, hell its encouraged to promote visibility.) I don't want to see an echo chamber style of discussion, or for minority opinions to be punished. I want to drive more player to player communication not OP to player, so take a moment and look if any one has shared what you wanted to say then add your post to theirs. If your going to disagree please provide if its from personal experience or share data you feel is relevant. If the above is an issue or you don't wish to participate, I tried to provide a multifaceted poll so your welcome to make your opinion visible.
