And now I won another game and my rank went down AGAIN

So Mark has provided hope that the current system will be improved, acknowledging that it’s not an ideal experience.

Meanwhile a reminder about what is going on in the calculation:

"The" explanation of why your rank can go down after winning a game

Do I get this right: Your new rank is calculated from your rank 15 games ago, plus the effect of the most recent 15 games. If that game, 15 games ago, was a loss where your rank went down from before, then your starting point for the calculation is now lower than it was last time your rank was calculated.
