    THe new method how to always increase your mmr:

    1. you play one game a day
    2. if you lose you play 1 more game
    3. stop for this day

    Lets calculate probability of winning MMR in those games. You get 0.5 chance to win 25 mmr in step 1. IN step 2 you either get 0 mmr when you win after losing or you get -25 mmr with probability of 0.25. Summing it up makes = 0.5*25+0-0.25*25=6.25 mmr

    That is your expected mmr gain per day. If you keep up with this progression then you gain 6.25*365=2281 mmr over 1 year. In 5 years you will be over 10k. That's quick math, fellows

      see you in 5 years when u gt 10k mmr man

        Thats not how statistic works (so wrong on many levels) and for sure not Dota^^.

        But actually its a good idea because after 2 looses you are already a bit tilted and tired. Just stop at try it the next day. I only loose MMR when I play like 8 games in a row to gain MMR back. Sadly thats my way of playing ranked :(

          No, your maths is flawed. In your 'step 2', you say that 'you either get 0 mmr when you win after losing or you get -25 mmr with probability of 0.2'. Now, the problem is when you consider the net mmr loss as -25, it is actually -50 as you have lost 2 games in a row. Thus, the sum is 0.5*25+0-0.25*50=0 mmr.
          Please don't mislead people with flawed mathematics; inherently, and intuitively, the mmr change over time should be 0 if you're already at where you're supposed to be.

              you lose 50 mmr in case 2.
              So you have 50% chance of +25, 25% chance of +0 and 25% chance of -50. Guess what the average of that is.

              You thought you could trick the casino?

                He didnt say he is good at math, he said he is good at getting mmr :P

                      So true.makea sense.The more games played in a bad day the more chance of ranking down.
