enthusiasm starts at base 5 (at the start of every season) it increases by 30% every time you use the TIE (or take it easy) after the game it starts to decrease and revert back to its original base which is 5. Scrimmages don't allow you to use the TIE option. So if your current enthusiasm is 5 and you use tie it will be 6+ the next game you play. If you decide to take it easy again it will be around 8+ next game. the highest enthusiasm will go is 15 but come game time you are really looking at 12+ maximum and if you are already out of the CUP 10 or 11 might be the max, because you cannot use TIE in scrimmage games
