1. Swiss system +. Just one thing, I still think that if they didn't manage to play, give them 1-2 days to finish the game, otherwise, both players get 0 points.
2. The deadlines are quite reasonable. As far as I remember, in the same beginner tournament, the deadlines are even tighter.
3. It's actually quite fun to play, let's say, in a non-standard way. But 200% is definitely too much... and it's chaos. I'm in favor of a full random setup.
P.S. To somehow diversify such templates as Heroes of Might and Magic VI or Might & Magic: Heroes X, a good idea would be to change the colors :D
