How does performance based SR actually work?

Like…what is taken into account? How can it tell how well or how poorly someone performs? Is it a strict numbers thing? Because that lends itself quite easily to spamming and fudging statistics in order to get more SR. As well…how much does it actually affect SR gain? Does it only influence gain or loss by 2 or 3 points? or something more dramatic like 10-15 points?

I’m just curious as it seems that you do really well one game and you gain 23SR. Next game you just barely lose and it takes you down 23 SR back to exactly where you were. So how much does it actually play a role?

at this point I don’t even think the people who designed the system knows for sure, given that I can play my butt off and get 15 SR for a win, and other games I feel like I contributed next to nothing and was literally carried and get close to 30

It’s based on “on fire” percentage versus expected percentage on fire.

For example, a gold soldier might “supposed” to be on fire 15% of the time. If they’re on fire 16%+ of the time they get extra SR and vice versus.

Think like this:
A base win/loss is 25 SR. PBSR works off this based on your stats on your heroes per ten minutes compared to everyone else your rank on that hero on that map.

Say on Anubis winning Ashes in Gold do 9000 damage/10 minutes.

You win but did 10,000: you get say 1-5 SR on top of the base
You lose but did 10,000: your loss is cushioned by say redacting 1-5 SR lost
You win but did 8000: your gains are reduced by say 1-5 SR
You lost but did 8000: your losses are penalized further by a greater loss of 1-5

Now do this for every stat, factor in win chance from matchmaker, your proximity to your MMR, your MMR’s confidence, and a million other things and you get what results in PBSR for sub diamond ranks.

Focus on winning, on having fun, on improving your stats (something like Overbuff gives you a good idea of how you stack up), and in time, if you improve, you’ll see SR gains. Focus on skill; SR will follow.

So…in other words…it’s stupid? Because way more goes into performance than raw numbers.

I would think this is one of the dumbest metrics possible. You get fire just sitting on point… How long you’re on it seems like a really dumb way to measure success. I think Fire really just contributes to POTGs and is an indicator of success (kinda) but misleading like medals.

Not imo. I think it’s a way to show success v not as it tries to keep players where they belong not be punished/benefited by luck. It kinda gives benchmarks by stats as to where you should be if in X range. It accelerates your climb as well provided you’re doing well. It’s taking the winning stats so it’s a safe metric as to what you should be doing to succeed.

But what about tanks? What about rein? He does way more than damage, elims, blocking damage…Just because he blocked a lot of damage doesn’t mean it meant anything. Or just because he did a lot of damage doesn’t mean he protected his team and did a good job as a tank.

it doesn’t, it messes up peoples SR and puts people into SR way outside their actual skill

Agreed fully! Stats tell part of the story though. Hence wins/losses matter most. If they are just stat farming odds are they won’t win so it won’t matter.

How would any system measure call outs, space created, pathing, etc? It’s just not really possible…

Yes but if that’s all you do to contribute to fire you won’t be on fire often. You need to heal, do damage, get kills, shut down ults, sleep darts, etc

I believe it’s stats AND win or lose.

As mentioned you could farm stats and have lots of blocked damage as Rein, but your team still loses, it doesn’t matter then.

It’s about generally having stats that are above average for what is expected of you in that rank, which across the board will be relatively the same.

For example a widow that belongs in gold is going to have similar accuracy to a widow that belongs in GM, because her opponents are relative to her ability to hit the target.

#1 Widow has 48% accuracy. The top widow still misses more shots than she hits BUT if she was playing down in gold, you can bet she’d probably have a 60%-70% accuracy and so these are the sort of stats that are taken into consideration when rewarding SR.

Also there is a factor of probability of winning the game. If OW thinks one team has an advantage or disadvantage, this also affects the amount of SR gained/lost

Pretty sure I read somewhere it has nothing to do with being on fire…(I think!)

Quote from one of the dev’s Scott Mercer

The change to the handling of assists also affected how often a player might earn “On Fire” status during a match, but the amount a player is “On Fire” does not directly affect SR adjustments due to player performance. There is some correlation between the two because both systems are trying to measure “How well are you playing?”, but there are significant differences. The determination of being “On Fire” examines not just your own performance, but your performance relative to your teammates. The calculation of your SR adjustment after a match doesn’t look at your teammates, but instead compares you to the performance of other similarly skilled players with that hero across an enormous pool of competitive matches. So, we compare your Genji play to the play of other Genjis, Ana vs. Anas, etc. Since we’re comparing “apples to apples”, we shouldn’t see any kind of support specific bias in SR adjustments due to player performance.
