I'm not too sure if the goal of setting up lower ticket prices so the dropoff after a loss is compatible with trying to maximize revenues...
That said, I'm not too familiar with div.1 arenas, but your set up looks good so far. I'd stop constructing seats, and start experimenting by slowly adjusting prices using some of the other good div.1 teams as examples (which it seems you've been doing, except BC Törööö is inactive so that may not be the best example). I may start by trying to increase luxury box prices, but that's just a guess.
