When reading to your thread I was developing a theory like '1st game was probably against a team on the upper part of the chart, and 2nd game -low attendance one- probably with one on the low side of the chart' but then after checking it I see both rivals are in similar position. So for me it does feels a bit too much of a drop -considering prices remained the same-. When trying to understand the attendance in my arena, I do think there is a factor where the attendance is way better with better teams rather with the bad ones (look at my IV Spanish league where there are good teams and almost bot ones). I myself also had a huge drop last game after losing against my direct rival, increasing slightly the price and playing against a fairly worse team, so it makes more sense in my case than yours.
