            your 
            arguments 
            about 
            separating 
            1v1 
            and 
            team 
            ratings 
            are 
            valid.
             
            And 
            there 
            are 
            also 
            arguments 
            against 
            it.
             
            For 
            example 
            it 
            can 
            be 
            good 
            to 
            separate 
            ratings 
            for 
            players 
            who 
            play 
            10 
            games 
            a 
            day,
             
            but 
            there 
            are 
            also 
            players 
            who 
            play 
            2 
            games 
            per 
            month.
             
            If 
            they 
            are 
            played 
            on 
            troll 
            maps,
             
            it 
            can 
            be 
            better 
            to 
            include 
            them 
            to 
            everything. | 1 | @malric 
            those 
            are 
            good 
            questions.
             
            It 
            seems 
            casual 
            rating 
            is 
            impacted 
            by 
            all 
            games 
            (
            not 
            sure 
            about 
            noelo 
            and 
            silly 
            maps,
             
            though)
            .
             
            @Godde's 
            change 
            seems 
            to 
            be 
            due 
            to 
            the 
            hourly 
            recomputation 
            based 
            on 
            his 
            1v1 
            games.
             
            AFAIK 
            team 
            balance 
            only 
            uses 
            rating 
            average 
            currently.

                    |  |  | 3 | @Godde your arguments about separating 1v1 and team ratings are valid. And there are also arguments against it. For example, it can be good to separate ratings for players who play 10 games a day, but there are also players who play 2 games per month. If they are played on troll maps, it can be better to include them to everything. |

                    | 3 | How all those arguments weigh for prediction/balance quality on the whole can only be shown mathematically. I suppose this is what @DeinFreund did, so I trust what he says. | 5 | How all those arguments weigh for prediction/balance quality on the whole can only be shown mathematically.
