In a way that allows you to win a higher percentage of your games. I’m going away from keyboard for a while.

My game data from 2 seasons makes me say it. I can even shout it out loud.
I’ll give you and example.

My games with Dva, same SR, very close performance stats. PBSR bonus completely gone. Why? Because of team SR difference. These SR fluctuations due to factors out of player’s control should go. This is what makes the community so toxic in large part.

16

I think the SR difference should play a part, how big? I don’t know but it should be a factor. But usually its your SR compared to the average SR of the other team. That being said, it looks at your stats PER 10min, so if your stats are similar but if one game was 5 minutes longer, it would make sense that even if your stats were slightly worse you gain more because you had better stats per 10 minutes.
Also, what does the bl mean in 2000bl and 5900bl mean?

17

If you have a look at Kabaj data from Kaa’s spreadsheet, you will see - team sr difference has little to no impact on resulting sr. And this is the way it should be. Think about it: did you choose those teammates and enemies? Did you specify desired sr range beforhand? Did you define grouping between ranks allowance? No. Then why these factors should nullify your personal impact?
2000bl means “2000 damage blocked”, 6900bl is “6900 damage blocked”

awesome work! thank you. do you have any idea how many points are normally attributed to PBSR. I would say at most 4 points on a 24sr win/loss.

My best guess is, if you have an above average game you’ll get an extra 1 point of SR but if you have a really really good game, you’ll get 2 bonus SR points. Thoughts? thanks

We’ve talked about expected win percentage and the effect on SR at length elsewhere (How Competitive Skill Rating Works (Season 11) - #61 by Oldphardt-2154 post 61 and following for those who may be interested). I don’t have anything new to say on the topic.

When Blizzard removed PBSR for 3000+, there was a lot of agitation to remove it for everyone. The requests were ignored. But then, Blizzard often does implement what the community wants … eventually, so we will see.

And of course, the community is not of one voice on this. There are certainly people who complain that win/loss is the most important factor in ranking up.

My opinion is that performance modifiers do help move new players where they belong much faster than an Elo type system, so I propose that the performance modifier be removed for Bronze to Platinum players after a sufficient number of competitive games has been played. Blizzard can use their data to determine how long it takes for people for their rank to stabilize, which would be a good place for a cutoff.

I have trouble quantifying it, but roughly +/- 4 SR. For people in high bronze to plat, finding fair matches is not difficult, so most deflection from 24 is likely due to performance SR. If you are misranked, I suspect the value can get larger, but I don’t have any data.

someone did the math on here and there are about 460 ways to cycle 11 different players to make a match for you. So once you’ve played about 700 games, your SR can be relatively certain to be relatively accurate :slight_smile:

22

Kaawumba, do you think, there is any point in analyzing the pattern in team SR difference? I can clearly see it, judging by my data and your data from top guys’ matches. Top guys certainly have some insane team SR differences, but in lower ranks these 30 average SR play a huge role, with PBSR in effect.
Maybe there is some math in play?

23

Whats the use for this exactly?

24

The team SRs are averages of the public SRs, so they include decay. As such, they are not as useful in diamond+ as we might hope. I still record them anyways, because I can. I look at and analyze them from time to time, but haven’t found anything interesting enough to post.

Your data I am interested in, but the error bars are still too big to demonstrate the effect that I’m looking for, unfortunately. I’m continuing to follow and watching as the error bars shrink with more data.

Ok. I’m already in placements on new account. I wonder how will they turn out :slight_smile:

27

Here’s what I was talking about. If everyone is forced to use this system, the worst that can happen is that it will all equal out in the end and they wasted a bunch of money and queue times are longer. but aside from that, it’s a win win :slight_smile:

My proposal:

If I win a game of Comp, give all five of my teammates 1 point.
If I loose a game of Comp, give all five of my teammates negative 1 point.
When queueing prefer people with the most points.
After in queue for 5 minutes, disregard all points and find me a match ASAP.

This could all work in the background, or we could be shown what our teammates’ current point tally is.

You can opt out of giving points, but can’t opt out of having points given to you.
You can toggle the queue time thingy too. Like make it 5,10 or 15 minutes, or forever.

On my alt account,

I started to gain 50 sr per win for the last 3 games, I am on a 10 game winning streak but I don’t remember matchmaking giving me this much sr even on a streak since season 3, is the modifier for winning streaks back? Any news on this? I thought winning streak modifiers were negligible, since season 3. Keep in mind this is diamond with no performance based sr.

29

This is probably why it won’t happen. High cost, small benefit. Note how they moved from two to three “avoid this player” and acted like it is a big deal. They are very worried about queue times going up. Whether or not this fear is justified is something I can’t see with out Blizzard’s internal data.

How long has it been since you’ve played on that account? Inactive accounts get their uncertainty modifier bumped up so you gain/lose more per game. And if you keep winning, I expect that uncertainty modifier remains high for a while.

It’s not streaks. See Streamer Data - Google Sheets → Dmum 11, which was a new account, and has 18 wins in a row, with steadily decreasing gains as his account loses the new account uncertainty. If you give me your SR after each game this season, I may be able to say more.

31

All that hard work means nothing, because everyone’s still hardstuck in plat :smile:

LULxD Your hard work and knowledge means nothing because it’s 2018, OP!

32

It has 32 hours of comp history but with really good stats and I skipped two or 3 seasons.

My friends started getting 50 sr per win too, perhaps my sr is trying to catch up to my mmr since my stats are so high?

I averaged 37 sr per win yesterday. Super strange in diamond.

33

This is why. Reread my first reply to you, and let me know if and how it is not clear. As you play more and your rating uncertainty goes down, your gains will fall down to the normal +/- 24.

No. As you’ve said, performance doesn’t matter in diamond+.

I’d ask your friends the same questions I asked you.
