MMR Accuracy?

Bent Pixels·Mar 6, 2018·1 votes·363 views

According to my op.gg, my average MMR for Bronze 5 (please dont flame me im trying my best lmao) 50 LP is 839, and the average for B5 50 LP is apparently 912. This, however, doesnt make any sense at all. Idk if MMR accounts for ALL games (including blind pick and unranked draft) or just ranked ones, but if youll scroll down through all my recent games, it shows that i havent had an MMR rating per game of below like 930. Is MMR suppose to be this inaccurate?

Can someone just explain to me how MMR works and shit?

Thanks!

First off, only ranked games. Secondly, it shows you the accuracy of the most recent -1 game (as i know you just got out and haven't checked if it was a loss or a win yet) so it's off of where you should be. Thirdly it is the AVERAGE of B5. This means some days it might be 912 MMR and sometimes it could be as low as 600 MMR (not real numbers for it but you get the idea). It isn't saying you're bad or anything by the means. You shouldn't go off of the average if it is too high. If you win 3 games in a row or just 2 win then 1 loss then 2 win (2W 1L 2W) in a row then you should have the same MMR as a 3 win row then some. Again, op.gg is a free service that is not official by Riot as far as i am currently aware so don't give me hate on it if i'm not accurate.

You have a separate mmr for every queue type, so your normals mmr is different from your ranked solo mmr which is different from your aram mmr which is different from your rank flex mmr and so on.

Op.gg and similar only estimates ranked solo mmr, and furthermore it's only an estimate. The only way to get a hint about your true mmr is by looking at your LP gains/losses. If you're losing more than you gain, your mmr is below average. If you're gain and losing about the same (~20) your mmr is about right for your rank, and if you're gaining more than you lose than your mmr is higher than expected.

Also, the estimates (emphasis on estimates) of mmr op.gg gives for matches would be the average mmr for all those in the match, and it's quite possible that the average mmr for the match could be 900 while you are 800 if there was a >900 player to balance you out. Matchmaking tries to keep people with close mmrs together, but at very high mmrs (i.e. challenger) and very low (i.e. bronze 5) theres not necessarily enough people with similar mmr all queuing at the same time, so as a b5 you may find yourself playing with slightly higher mmr players more often than not. (This does mean if you win, your mmr gains will be better than if you wons games with everyone being the same mmr as you however.)
