What about the statistics of ranges?

Today while doing a stream by raising my ranks, I won several games and NONE gave me% to go up, I lost a game and I lost more than 10%, as much as I and my audience we were amazed with this “injustice” (no I know if you can tell him) because you try hard in every game to climb and it can not be possible that in a loss you LOSE MUCH MORE THAN WHAT YOU CAN WIN. My viewers like me do not explain how something can happen if.
please fix it, for things to do, discourage play :frowning:
