Competitive Ranking Issues (1CSR Per Win)

I’ve been having this issue on and off for the past 3 seasons. My CSR goes up 1 or 2 points per win, yet de-ranks 10-20 per loss. I’ve had this problem on and off for the past 4 seasons. Last season it started around 2,300 csr, and this season right after placing.

This is an extremely frustrating experience and has forced me to use alternate accounts, though I want to use my main for many reasons.

Some kind of response and hopefully a resolve would be great.
