If their mmr is plat they get put into plat games. If their mmr was high enough for an immediate streak of 5 gm games they wouldn’t have been matched to plat but instead to masters or something.
I actually had an account that was boosted from plat to masters at season end since it had a silly winrate. Then got put into masters/gm games. The game matched the mmr to sr and the lobbies you get placed into are based on mmr. Their rank was their matchmaking rank.
Not if the system SUSPECTS they are not plat.
Look, the person was Obviously able to play in GM, WHEN it was the GM person playing the account right?
In which case they would have been boosted at season end to match their mmr despite no extra games played. As in close the game as plat, next time you logged in it was masters. That didn’t happen since their mmr wasn’t higher than plat.
Look, I will make it simple.
If a GM smurf was playing on the account, it being placed into GM quickly, isn’t a failure of the matchmaker.
It is doing what the matchmaker is MEANT to do, quickly moving the account to the level of the person playing on the account.
Saying that it is a failure of the matchmaker, is not understanding the job of the matchmaker.
Having the matchmaker not match your mental model of how it works, ALSO isn’t a failure of the matchmaker. It could be a failure of Blizzards communications, but that isn’t anything new.
The evidence doesn’t show that though.
Even if we accept that they went from bronze to plat with a gm player on the account their mmr was still plat at season end. Where was the end of season boost from matching sr to mmr?
Even with uncertainty putting them into gm mmr from there is broken/terribly designed as that’s too far away from where the system determined their mmr to be. Diamond? Sure. Masters at a push? Ehhh now it’s getting silly.
Because they’re using both upper and lower body strength.
It could have dipped hard before doing this, or started much lower. if the account was playing as a Bronze, before this. Remember you will saying it had a 20% win rate.
Again…
ANOTHER system should have triggered to say “I think there is cheating going on here” and suspended the account.
But that isn’t the matchmaker.
This might take a minute…
Ok. So lets say someone played it through bronze, to silver and get boosted to plat since they had a high winrate at season end.
In no world does a good system immediately go “try some gm games” based on beating low metal ranks. Even if they had 100% winrate for 50 games that’s absolute insanity. I could see your argument if they threw them into high diamond games or something but straight into gm? No.
That could have easily been playing diamond/masters games at this stage, another couple of wins, and they are playing GM.
Again. If a smurf is on the account the landing them in GM quickly is the matchmaker working.
ANOTHER system should have triggered to say “I think there is cheating going on here” and suspended the account, for review, but that isn’t the matchmaker.
The matchmakers job is “if someone takes up playing the account at GM level, place him quickly in GM”
No, since that would mean their mmr was diamond/masters so they would have been boosted to match that mmr. I know this to be the case since it happened to some of my accounts.
Again…
To sum it up, just because you think it should be recording their MMR as diamond / masters, when it isn’t sure they are meant to be there, and are testing them, it doesn’t make it so.
A working matchmaker CAN act this way.
Rusalka (my matchmaker) DOES act this way. It stores a probability curve for where it thinks the person is. It reports MMR as a simplification of that curve.
Again, matchmakers jobs are to place you quickly in the rank you are playing at.
You’re put into games based on your mmr and they matched your mmr to rank. They were in plat games at season end. Anyone playing above their rank was boosted to that rank. Even with uncertainty we’re not talking 500sr difference or something here. It’s 1500 sr difference. That’s not uncertainty. That’s completely wrong with an adjustment time of 5 wins for such a massive increase.
There’s no way to argue that 1500sr should be gained from winning 5 games. No matchmaker can function like that.
If a GM is playing on the account it would be correct IN that level of uncertainty. That isn’t it failing.
Take MS’s matchmaker.
TrueSkill is a Bayesian skill rating algorithm used worldwide, it also uses the uncertainty system.
TrueSkill II uses the same kind of curve maths that Rusalka uses.
The uncertainty was addressed with the end of season matching sr to mmr.
It is. A diamond could realistically win 5 gm games in a row if they were somewhat lucky. 5 games just isn’t enough to determine somebody needs to go from plat to gm. No matter the winstreak they had previously.
No it isn’t. The system knows it still has no idea what the MMR of this person is.
Good thing it knows more than that. It’s internal stats from last season are not lost to the wind.
If it had no idea there was no reason to give them a plat to gm update based on 5 wins. If it’s uncertain there should/would have been an increase to diamond or something.
I don’t know how many times I have to write this… but…
It’s job is to land the person at their correct MMR as quickly as it can. It can do this in a way which you can find mystifying or against what you believe in, but it doesn’t mean it doesn’t work.
Matchmakers are not designed to handle smurfing. That is an enforcement problem.
You’re put into games based on your mmr, correct?
Yes, but if your MMR is a curve with a couple of lumps, it may not place you in games based on the simplified displayed SR.
There is no reason to believe MMR is a number in a single dimension or that the simplified display of it, matches the matches you are placed in.
Again, not the matchmakers problem.
