Yes that makes sense, however the example i have is the reverse. I started my first alternate account expecting to be lower than my main was at the time which was silver 3. When i finished leveling the account and finished placements, the account ranked at gold 3. I then climbed that account to gold 1 over the course of about 30-50 matches. When i tried to push my main account to gold afterwards, it was hardstuck at silver 2 and 3. I would switch back and forth between the accounts, and found i would win and climb much easier with the gold account than with the silver account.

Since then, ive abandoned two other accounts because a newer account climbed past the old one, while the old one seemed to be hardstuck. One of the things i noticed while climbing different accounts was the difference in LP gained and lost on the account with lots of games was always less, even with a much higher win streak(10-20 win streak vs 5-10).

If the system is built to always put me whe...

Sure, if you want to send along the summoner names I can probably give you a better answer. There's a lot of components to Ranked so it can be hard to explain with incomplete info!

Thank you so much for sticking around replying to every comment, Im reading every single one and it's honestly refreshing to hear about this matter from Riot itself.

May I ask you to clear up a thing about mmr? If you're allowed to say it ofc. Can you confirm that LPs gains are exclusively dependant on win/lose at that given mmr (and how big is the difference between your personal mmr and game average mmr between the 10 players) and that win/lose is the only factor taken into consideration for mmr variations?

Basically, is win/lose the only stat that matters to the system? Aka game performance by stats (kda, vision score etc) are totally irrelevant? Im asking this because in s9 many people are still not sure about this and I've seen some people spreading what I think is misinformation, and there's no official source for people to actually verify this.

Thanks in advance, Im no native speaker, I hope it wasnt too confusing to read.

I'm definitely not getting to all of them - I still occasionally have to do work ><

We don't take KDA, Vision Score, etc. into account for MMR, because those statistics are gameable. We don't want to create a situation where your support decides their odds of winning the game are too low, so they instead focus on maxing out Vision score to save as much MMR/LP as possible.

It's this weird problem where those stats are really great for figuring out how good a player is - right up until the player realizes they're being measured on those stats.

Yeah, I think this is a really good point - I'm going to look into how we can change this experience. It does seem silly for us to say, "Hey you're blasting off at the start of the season!" and then jump you a bunch AFTER that's done

Thanks for the reply.

The thing that has always confused/bothered me is the fact that I can end up in a situation, where I'm playing my promotion series, for example, to get into Gold 1, BUT I am playing versus Plat players. And if I fail to win those games, the LP system determines that I am not good enough to be Gold 1, when in reality I was tested against Plat players. Do you see the disconnect here? My arbitrary solution would be to compose teams from within the same LP division, and if I am in promos to Gold 1, then I should be playing versus Gold 1 opponents.

I get that it's almost impossible to create such a system and that could lead to a multitude of problems which I am not considering right now, but can you imagine how my previously proposed example could be disheartening?

As for the other accounts, that wasn't really a complaint on how the new accounts work, cause I understand the principle. I use the additional accounts to play different roles,...

Totally get the disconnect here - and something we'd like to improve in the future. It's unfortunately not as easy as guaranteeing you have Gold I opponents, because not all Gold I players have the same skill (including you - from what it sounds like, you may be climbing upward and have a higher MMR than your current Rank).

In general, we match on skill rating, not rank, because skill rating matching creates matches that play more fairly, even if they sometimes LOOK less fair. Let's hypothetically say you are a player with Platinum skill, playing in Gold II. If we match you against Gold Is in your promos, you will have a much greater likelihood of winning, because we honestly think you're better than that - but this also means we've made a game where 5 players are heavily disadvantaged. Instead, we try to make a game we think is fair for you based on skill rating, and then let your LP move more quickly for each win in order to get your rank and skill caught up.

Not stupid at all! Normal MMR doesn't necessarily run on the same range as Ranked MMR, though, so the math gets a bit wonkier. But the general idea of using Normal MMR to inform (but not dictate) starting ranked MMR is good!

Can you explain how this can happen?

Some of our placement logic has changed over the year, and we do use information from previous seasons to inform some of our placements, and the opponents you played in those games may change how your skill rating (and thus eventually your Rank) changed over that time. There's basically a lot of factors here that could make your experiences different.

Have you experimented with systems similar to what Hearthstone does? (where everyone starts at the bottom of the ladder, and rank up as times goes on?) Even if the queues are perturbed longer in this scenario, I am pretty sure that it feels less shitty to go from Iron IV to Bronze IV than from Gold IV to Bronze IV and more players will be likely to approach the ranked queue. Having more high skill players joining the queue (your words) may only be showing that effect.

Furthermore, given that MMR is already hidden, the overall deflation in the system should be transparent to the matchmaking. You only care to keep the relative distribution of rankings accurately.

I love Hearthstone personally, so I'm pretty familiar with their ranked system! It works very well for a 1v1 game, because you can resolve differences between skill and rank really easily when you only have two players facing off.

Let's say a given player is Rank 2 skill, but currently Rank 6. In Hearthstone, they'll play other Rank 6 players, and on average, be better - so they move up! Their opponents, as average Rank 6 players, will probably lose when they hit the Above average player, but that won't be the norm and they will even out over time.

In League, we have to worry about teammates. This means that if you are Plat Skill but currently in Bronze, and we match you into games of Bronze Skill, you probably win more. But so do 4 of your teammates, and 5 of your opponents lose a game they had no chance at winning. The amount of disruption each of these games creates is 9x what Hearthstone experiences, and means that the system destabilizes much faster as players...

I know it's hard, and you get way too many suggestions, but why not weight initial MMR from norms? And also stop giving me 30% win rate people in my promos

Normals can be a part of the puzzle, but they don't perfectly correlate to skill in Ranked. It's probably a good thing for us to consider, but it's not the solution all by itself.

Why not have placements start lower and have win streaks worth more and loss streaks adjust match mmr more? I think the issue might be more the fact that the first two or three matches of a fresh account starts at gold, which is basically a coin flip of it being a new player, a bronze "smurf", or a high elo smurf.

I also have a question, why can i climb so much faster and easier on an account that has less games than another at the same elo? Example, having 100 games played at gold 3 vs 300 at gold 3. My 100 games account will climb much faster than my 300 games. This means i abandon an account every time an older one catches up, and so far its been too consistent to not be design. Is there no limit to how the system judges your improvement with games played?(i.e., judging it against a 300 game sample size instead of capping it at say the last 100 games sample size)

We match based on MMR, not Rank, so starting placements lower rank-wise wouldn't matter. If we started at a lower MMR, as I mentioned in the original post, it just ends up moving the middle downward and destabilizing more games along the way.

As for account age vs. climbing, I may be misunderstanding your example, but let's say you have a 300 game account that is settled in at Gold III. Then, you make a new account and play some games, and rise quickly to Gold III - much faster than the 300 games you played on the last account.

What you're not taking into account is that on the older account, you weren't necessarily at Gold III skill the entire time. Over the course of those 300 games, your skill changed and improved up to Gold III, and your MMR and Rank changed to follow. Now when you make a new account, your skill is starting at Gold III, and your MMR will adjust to that very quickly. Since you weren't the same player when you started the second account, you shoul...

A while back, you guys changed the API so websites like op.gg can no longer display MMR. Is it possible to get that feature back ? Perhaps in the main client ?

We don't plan on bringing visible MMR back - when MMR is working correctly, it does a lot of things that feel bad when you look at it in isolation. The biggest one is that for half the population, MMR only goes down, because we start people in the middle and then naturally, half the population has to be the bottom half.

As a side note, the API was not sending MMRs out to third party sites, that was a separate estimation done by those places. Part of the reason we asked for it to be removed was that it was often substantially wrong and led to a lot of false expectations.

Are winrates not taken into account? I’ve seen so many people with 70-80%+ winrates in mid/low gold with like 40-50 games versus someone with <48% winrate with hundreds of games

Winrates are a very fuzzy metric, because they don't take into account who you won against. A lot of new accounts that eventually reach Diamond+ will start with 70 or 80% winrates, because they're a Diamond skilled player facing off against Gold skilled opposition. But as they move through the ranks and face harder opponents, their winrate will go down. That doesn't mean they've gotten worse - it means we've gotten enough information to give them more fair games.

How does the system determine the final rank though? After losing first game in my placements and finishing around 7-3 I was placed in Silver 1, but after another win the system bumped me up to gold 4. Wouldn't it make more more sense to do adjustments like these in placement games? Or is it that MMR and rank need to be far enough apart for this kind of jump to occur at any point?

So provisional games aren't meant to mark the best rank you can achieve, just where you're starting your season. From your particular case, it sounds like you ended right on the threshold of Silver I and Gold IV, so as you won more games, it makes sense that you'd move upwards.

One thing I've been wondering though. Wouldn't be feasible to look at the input stream from a player and apply an algorithm to judge the mmr? I don't know if this is part of smurf detection or mmr already, but I'm thinking that a deep learning network would be farily good at guessing the real mmr of a player given the proper input and also quite resistant to trying to gaming it?

So generally I agree, but tuning those kinds of models is not super easy, and can run into issues where once you've tuned it, you may promote strategies that focus on convincing the system you're good rather than actually winning the game. We are experimenting with some options along these lines, though, and they show promise.

Hi, Can you please provide an explanation why there is such a significant divide between hidden MMR and the LP system? And I am not talking about new players here, so pardon for going off the topic of the OP.

If a player is consistently matched with people above his current division/LP, shouldn't he be promoted to the same rank as the people he's playing against? Why employ arbitrary limitations to LP gain maxing out at 35 or so LP per win, and limiting division jumps to 2 divisions (from what I've experienced myself. Not to mention that these jumps only happen if you REALLY shouldn't be in your current LP rank).

This is an issue I've faced in all of my accounts, where the MMR gains outpace the LP gains and I end up playing versus players with higher LP ranks than me. When I play Support on my main, I get to Gold 2 or so, and get matched with Plat players, but I struggle to reach plat myself due to the limited amount of games I have time to play. I know that with an...

So MMR is meant to measure your skill, and that is all it's meant to care about. This means that we want it to be able to adapt quickly, be fine with overestimating, and move around quickly as we get new info.

LP is meant to be more steady and certain, so it moves slower and is less responsive to small trends. This is why it takes more games for your LP to move upwards and sometimes catch up with your MMR - it's effectively waiting for a larger sample size.

Also, if you are making new accounts (which I'm inferring from your post), it's going to take longer for your LP to catch up, because again, we're starting over from new info each time.

Why dont you factor in normal game mmr for the few first ranked game

if someone is getting shit on by bronze players in normal why toss them into mid gold mmr in their first ranked game

Normal games may be part of the answer, but results in Normals don't necessarily correlate 100% to results in Ranked. People don't always have the same competitive intent in Normal mode, so a player of average skill who tries hard may be slightly above average in normals, while a player of above average skill who messes around may end up below average. Then when those two players go into Ranked and start both trying hard, their Normal MMR wouldn't actually reflect their relative skill.

It is a good starting place, though!

Wouldn't it be possible to split up mmr for new players? Just hear me out.

The initial mmr's would be on one side the average mmr a new account has after like 20 games, and on the other side the actual average mmr of the ranked playerbase. Would it not be possible to have matchmaking (and visible rank) based on the 1st mmr, but have the 2nd there to keep the ranked system in balance?

Eventually both mmr's should meet in the middle since the 2nd one barely has any gains and significant losses.

Does this make any sense?

Yup, get where you're coming from on this, and it's a cool idea! But it's operating on the assumption that new players fall between those two points. We don't necessarily know that to be true (and in the specific case of saying they should be between average and somewhere below average, we actually KNOW that isn't true - many new accounts are above average skill).

There's probably a version of this where you could pick a point below average and a point above average, and execute the same function - but this would still constrain players into that range for their first few games, and do a poor job of handling outliers who are either really good or really bad. And for players who are really good, we'd be dropping them into below-average skill games for much longer, which makes those matches feel unfair to the players who really fit into those games.

I imagine guaranteeing stability, no rank inflation, ... is much more difficult. But it may be more representative and allow you to adress some of these issues.

We try to model our skill estimation to the results we get, not towards a particular shape of a distribution we have in mind before starting. So aiming for a bottom-heavy distribution wouldn't necessarily be representative of the data we see in game.

I just made a support ticket to see why they locked my account and what was so suspect about it, except for the fact i was clapping up some kids as TF ;).

I got question for you then. Why do I end placements in silver or even bronze, with 9/1 placements, where last few games were wins in high gold/low plat elo. Last few wins in placements give +40ish lp. After placements 1st win skips you 2 divs. Next 3 wins give up to 38 lp, and after you pass 100 lp you just go to next div without promos.

So why are next 10-20 games after placements more influential than 10 placement games themselves. 1/9 or 9/1 no difference at all, it is all about next 20ish games after placements.

While I'd disagree that provisional games are less impactful than post-placement games, you do make a good point that since you can't skip divisions during provisionals, you may get bigger single game jumps, depending on where and when those wins happen.

Some atypical things do happen when you go 9/1 or 10/0 in provisionals, though - I think this is more a product of you having an excellent win streak and the system cautiously catching you up than anything else.
