Hi, I'm Fralu,
I report the error that I enclose in the calculation of the count. It is not the first time that the following has happened to me:

I lost a match on 02/19/2021 against an opponent (Murat84) and I lost 11 points as per your calculation. However, 33 points were deducted from my overall score as you can see from the player's information. How is it possible?
I would be willing to sign up but not with these obvious errors.
I am waiting for your reply.
Thank you,
Luigi
