4) Maximum enthusiasm value right before the match seems to be 12. The real outcome is 11,62174. It could be gotten by playing TIE in all the matches (League and Cup), not sooner than on Week 9 Saturday - before the match.
I have played TIE in each game so far this season (6 league games, 3 cup games), and after the daily update that occurred a few minutes ago it appears that I will be entering my game tonight with enthusiasm of 12... the Saturday of Week 4.
