So enthusiasm loss over time is always proportional to how far you are away from 5 enth. What changes is how much enth is consumed in a game. POCT acts like regular Normal in that enthusiasm drops as if there were no game. PON acts like regular TIE in that it adds enthusiasm. Now usually you have a few days between games which diminishes the separation you get from having an effort mismatch (since the team with higher enth will lose enth more quickly). But since game 2 and game 3 are on consecutive days, you get more separation out of the effort mismatch than any other time in the season.
