Inaccuracy of elo ratings

The worst thing you can do about chess is carrying about your elo ratings on online platforms. Because elo ratings are highly inaccurate because of matchmaking algorithms. They put you purposely on winning and losing streaks for keeping you enrolled and your elo rise or collapse dramatically. Thus you don’t improve effectively. You can see that especially when you play against lower elo players. The game you supposed be superior head to head. That is why it is best to play unranked games.
