Pawel is impossible to please every single player, take a look at your opponents, they are from all around the world is really impossible to please all. Even so, if you are from europe you can say your are "blessed" because your games are still at decent hours. Just think that you play at 8 and somebody from asia have that game at 12,1,2 a.m what about them? Or like you said 12 in the morning, what about people from US ? They will have the game at 4,5,6 in the morning.

8 hours between games are enough

Cheers!
