  • What's the difference between the ten placement matches and ones after

    I've been sticking with unranked so I clearly can't speak from experience. I'm just curious here, you need to play 10 games in Ranked que to get an mmr. However your ranked mmr is influnced from your hidden unranked mmr.

    So what goes on in these ten games that decide my MMR that's different?

    What I am asking is, what is the significance on the ten matches. Why not 5? Why not after 1? What am I missing?

    This is for my own curosity.

    Start with base 3500mmr before doing ranked

    Do first ranked game with other 3500 mmr players

    Win/loss has significant effect on mmr

    Repeat 9 more times, except significance decreases after each game

    See your now more accurate mmr


    Reason why its hidden is because your mmr is so warped in the first 10 games theres no point in seeing it.

      It starts with a base 3500 for everyone?

        No. It starts with your rating that is hidden in unranked. And no it doesnt have significant difference to normal ranked games. Basically its just an excuse for kids if they happen to have 2k rating. Did poorly in calibration matches so ended up in 2k... etc.

        There used to be console command so you could check your rating after each calibration game. Dont remember numbers anymore but atleast for me they werent that different to these +-25 games we get 90% of time.

          Okay, that's what I assumed. I mean if people started with a base of 3500 that's a pretty fucking important piece of info to know how to play that game, but I clearly misinterpreted it.

            I think the question you're asking is what's the significance of the number "10" right?

            None. It's arbitrary (to an extent), just like the science community accepting 5% as the statistically significant interval. It's the point in saying "Okay, that should be enough for practicality".

              Yes, predominantly because how I understand it was ranked mmr uses your unranked mmr as a starting point.

              I was wondering if those 10 games had any difference than say playing 10 more games in unranked and if not why can't they just tell me my mmr after one game cuz very lazy to play 10 ranked APs.

                You'd think the calibration matches would change your rank more than 25 points per game which would be different from juist playing 10 more unrannked.

                  Yes, one would.

                    handsonic has it right, if he's using 3500 as an example. The calibration matches are largely used to decrease "volatility", the system's way of measuring how accurate is your current rating? It's basically your standard deviation to your skill mean (MMR).

                      you start with your hidden mmr and through those 10 matches you get a visible mmr. those first 10 matches have a big impact on your rating for like 3 or 4 times the normal rating you would get which means a single match from those 10 matches can get you +/-100 points. There was a time you could see your ranked rating by playing just one game throught console by it got patched in like 2 or 3 days.

                        BTW, there is some math involved in determining what's statistically significant. The 5% margin didn't get pulled out from some old fart's ass.

                          I know. And we have Fisher to genuinely thank for all of that. At the same time, it is an arbitrary definition to say at which point the test becomes "significant"; it's not a natural phenomenon.
