[Milfar]

What's going on with your rating?
I have 4100, was 4590 (1 game left to win to get the rapier), profile decency 12000.
The last 30 games have gone like this
I win 1 game more or less average, not too hard and not too easy (40-55game)
the next game I lose by one goal, games last 15-25 minutes, with a score of 40-5 in favour of the enemy.
And so the last 30 games 1-2 win 1-2 lose automatically without a chance, what's going on in other ratings?
This is at any position.
Because I don't want to play this game anymore.
