Yeah, I only mentioned it because you said you sold out all your home games which is obviously not the case...even if the attendance losses were minimal.
However I am still fairly certain you are vastly overstating financial gains from your cup games. I seem to remember intakes of 15k and 20k more often than not.
I get around $200k per home league game. My arena was smaller then, so I was probably getting $150k per league game, so $75k for cup games. Not great, but not awful. (Again, I was lucky with home games.)
