your plan to tie those three games is good, your enthusiam will fall afterwards quite fast(it goes faster the higher the enthusiam is) but you will stay over 5 a while.
Crunch time during the season, makes mostly no sense, cause you notice it over a bunch of games. But if you manage your enthusiam well, your normal could be like a CT ;) I normally try to play 1 game tie each each week(+ a cup tie), but often you make two or sometimes none.
