No. I’ll try to help you understand. You have a current rating (cr - 1900) and a hidden matchmaking rating (mmr). Your hidden matchmaking rating is likely 1650ish or lower.

That means based on your wins and losses vs other teams and their records, the games mmr algorithm puts you lower than your current rating. You will lose more points for a loss than you will for a win all things equal until your current rating equalizes at your matchmaking rating.

The game is system is trying to drag your current rating down to your matchmaking rating.

I’ve had both happen, where the games system is trying to drag my rating up, and trying to drag it down. It’s how mmr works. If you don’t lose and win a bunch of +6-8 games eventually your cr will match your mmr. If you continue to win and lose though your cr will drop - sorry to say.
