Losing is losing. It doesn't matter how you lose/win the rating change against that particular opponent will be the same.
But your problem doesn't appear to be that. It looks like you lost rating after winning a game and that shouldn't happen. I would open a ticket and have staff look at it.
Hi there, I was doing OK and winning games. I lost the last two games, losing the right points average but last one by time more de two hundred points. Is that possible? was the reason losing by time? THANKS FOR ANSWERING
