I played two CT's in a row a while back, but to be honest I don't remember how fast it came back to 5. According to the math, your enth could have been as low as 2.5, which would then take you to 3.33 after the game. I'm not sure there is a normal daily enthusiasm update in the days after games, but assuming there is you should be really close to 3.5, and I imagine your enthusiasm will show up as "4" come Saturday's game time
