@Ray,
We have 3 standings: Public, Private and overall. However hosting a public cup only by TUS staff and letting others host their private cups is not a bad idea. I'll think about it.
@HHC,
It depends how we determine the bo5. If the mod, Only cares about the winner, Then the winner can report all 5 games in one shot and gain 5 points.
If the result is important like, 3-2. Then the winner reported 3 times and the loser reports 2 times. Winner gains 3 * 15 and loses 2 * 15. 5 points overall, Same for the loser. He loses 5 points.
