Hi! Is the order of reporting important or not?
For example I played  with Professor 3 trl games in a row:
1) https://www.tus-wa.com/leagues/game-91528/
2) https://www.tus-wa.com/leagues/game-91529/
3) https://www.tus-wa.com/leagues/game-91522/
He won first 2 games and I last one (91522). I waited half an hour until he reports but he didn't... so I reported first.
Did I lose any points comparing with the situation if he reported that 2 games first?

Yes, the order matters, you'd lose points in the case you described. The scores and ratings are recalculated after each game.

The games have been re-ordered now, so it's all fine.
